There are about 1320 clinical studies being (or have been) conducted in Saudi Arabia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.

This study is prospective cross-sectional collecting the data of patients according to daily standard medical practice
To evaluate the safety and efficacy of a daily, fixed-dose, 8-week course combination of Elbasvir/Grazoprevir in treatment-naïve, non-cirrhotic patients who are mono-infected with hepatitis C, genotype 4.
PURPOSE: The aim of the study is to compare visual acuity means, refractive results, safety, and efficacy of TPRK with AAPRK as primary outcomes and surgical time, pain scores, haze levels, and healing time as secondary outcomes. SETTING: Security Forces Hospital, Ophthalmology Department, Riyadh, Kingdom of Saudi Arabia. DESIGN: Prospective, consecutive, nonrandomized case-control comparative study. . METHODS: A total of 200 eyes of 100 patients were included. One hundred eyes underwent TPRK in the right eye (study group) and 100 eyes underwent AAPRK in the left eye (control group). Ablations performed with the Schwind Amaris, 750S. Clinical outcomes were compared Paired student's t-tests and Mann-Whitney tests were used for statistical analysis.
Background: The exit strategy after ureteroscopy for stone treatment remains a topic for discussion. Current EAU guidelines on urolithiasis state that postoperative stenting is indicated in patients at increased risk of postoperative complications. Stenting is not considered necessary in all other cases, and after uncomplicated procedures. Objective: To analyse the postoperative ureteral stenting strategy in clinical practice looking at the indication, type of stents used and the duration of stenting after ureteroscopy for stone treatment. Furthermore, the investigators will examine in what setting the stents are being removed postoperatively. Study design: This study is a prospective, observational, international, multicentre registry study executed by uCARE. Study population: All patients >18 years with a ureter or renal stone who are planned for ureteroscopic treatment by semi-rigid and/or flexible ureteroscopy are eligible for this study.
Double blind, randomized, placebo controlled, Phase 3 study to investigate the efficacy and safety of low doses and high doses of A4250 compared to placebo in children with progressive familial intrahepatic cholestasis (PFIC) types 1 and 2.
This research evaluates the effectiveness of video educations against patients fixed believes and knowledge that either not precise or overestimated, and compare with classic educational method such as Brochure. As many researches indicates the difficulties to initiate insulin therapy for type 2 diabetic patients due to overestimated barriers such as needle anxiety, feelings of guilt and failure, concerns about hypoglycemia, sense of loss of control over one's life and reduced quality of life. This research will introduce different educational tools to evaluate their effectiveness in breaking psychological insulin barriers.
To determine the maintenance dose of vitamin D supplementation required for children with epilepsy to maintain normal vitamin D level.
Research Problem: Upper respiratory infections (URIs) are a common reason for absence from schools as it is estimated that children get six to eight episodes every year. In Jazan (2013-2014), 34% of primary health care centre attendees who were complaining of URIs were under 15 years old and 42% of them were positive when tested for viruses by nasopharyngeal swabs. An intervention for URIs prevention is hand hygiene, as it has been shown to have an impact on reducing the risk of respiratory infections by 50% among children in Karachi, Pakistan by encouraging hand washing with soap. Another randomised controlled trial study conducted in Spain among primary school students showed a statistically significant 38% reduction in the absenteeism rate due to URIs in the intervention group who received education about hand hygiene and used hand sanitisers which were distributed among schools. Also, the Chinese conducted a cluster randomised control trial evaluating the effect of a hand washing programme and revealed a 38% reduction in absence due to URIs among primary schoolchildren. This preventive measure is questionable, as a randomised controlled trial done among primary school students in New Zealand revealed that encouraging the use of hand sanitisers in schools did not have an impact on reducing acute respiratory infections or absenteeism. The questionable effect was also documented in a systematic review and meta-analysis for randomised controlled trials about the effectiveness of hand hygiene in decreasing absences through illness in educational settings. Research Significance: Appropriate hand hygiene is recommended as a non-pharmacological preventive measure against respiratory infections. But this preventive measure is questionable as the results of randomised controlled trials about the effectiveness of different hand hygiene interventions in reducing absence due to upper respiratory tract infection in different educational settings are controversial. Furthermore, previous studies of hand hygiene interventions were low in quality and it is recommended to improve future studies relating to it. Also, there is no research on the effectiveness of these measures in Saudi Arabia. So, this piece will add new knowledge to local and international literature. In addition, this study may help the school health administration to develop a hand hygiene programme. Objectives: - To determine if hand hygiene education is associated with school absence rates due to URIs reduction among primary schoolgirls in Riyadh city, 2017-2018 - To measure post-intervention total primary schoolgirl's absence rate (both groups) in Riyadh city, 2017-2018. - To measure post-intervention primary schoolgirls' absence rate due to upper respiratory infections (both groups) in Riyadh city, 2017-2018. Methodology: Cluster RCT will be conducted among primary schoolgirls attending public schools in Riyadh city in the first education semester. Sampling will be multistage to end up with four schools. 616 schoolgirls who are attending the selected classes will be invited to the study. Two schools will be randomly assigned to the intervention, which includes one-hour hand washing workshop at the beginning of the study, in addition to posters. Parents will self-administer the questionnaire at baseline, in addition to a follow-up phone interview questionnaire.
Studies that give people vitamin D supplements to prevent caries have found that vitamin D is effective at preventing the development of caries. The aim of Study: To determine if there is a relationship between vitamin D deficiency and the development of Early Childhood Caries (ECC).
Abstract: Background: Circumferential negative pressure wound therapy (CNPWT) is commonly used to manage wounds and enhance the healing process. A theoretical concern was recently raised that CNPWT may have a negative effect on perfusion distally. Objectives: We aim to evaluate the effect of circumferential negative pressure therapy (CNPT) on distal O2 saturation in healthy volunteers. Design: Randomized controlled non-inferiority study. Methods: Fourteen healthy adult volunteers with O2 saturation ≥95% (by index finger pulse oximetry) will be invited to participate in the study. After obtaining a written informed consent, CNPWT foam/dressing will be applied in a sandwich-like manner on the middle third of each arm and a negative intermittent pressure of 125 mmHg will be applied to one arm chosen randomly, using the contralateral arm as control. The pressure will be applied 5 minutes on and 2 minutes off for 9 hours. Individual's participation will be terminated if O2 saturation drops below 92% at any study time. The outcome measure is index finger O2 saturation and will be checked every 30 minutes using a pulse oximetry. The area under the curve (AUC) of O2 saturation in the 2 arms will be compared using ANCOVA. Sample size was calculated to have 90% power, assuming a type one error of 5%, non-inferiority margin of 24 (mean AUC difference), SD of 20, and drop out of 2 participants. Importance: The study is expected to provide conclusive evidence on the effect of intermittent CNPT on distal O2 saturation. The results would have direct implications for CNPWT.
