Research Report clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Comparison of Three Summary of Finding Tables to Improve Understanding in the Presentation of Systematic Review Results

Start date: January 8, 2018
Phase: N/A
Study type: Interventional

Background: Summary of Findings (SoF) tables have been developed to present results of systematic reviews in a concise and explicit format. Adopted by many review groups including the Cochrane Collaboration, the Agency for Healthcare Research and Quality (AHRQ), and the GRADE Working Group; SoF tables provide succinct, transparent, and easily interpretable judgments about the certainty of evidence and magnitude of effects. Currently, there are three different SoF formats in use. This study aims to compare SoF table formats in terms of understanding, accessibility, satisfaction, and preference with systematic review users. Methods: The primary objective of this three-arm randomized controlled non-inferiority trial is to investigate whether an alternative GRADE-SoF table, or EPC-SoF table, is noninferior to the current GRADE-SoF table in the understanding of information presented to systematic review users. Researchers, clinical practice guideline developers, policy-makers, end-users, or knowledge transfer will be recruited. Data will be collected electronically at baseline and after randomization. Noninferiority would be declared if the difference in the proportion of participants who understand the information displayed in the alternative SoF table is 10% or less. Discussion: This study aims to assess the understanding, accessibility, satisfaction, and preference between three SoF tables for displaying summary evidence from health-related outcomes. The results of this study will provide important knowledge to understand what information should be included in SoF tables in systematic reviews.
