Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Composite of Adjudicated Major or Clinically Relevant Non-Major (CRNM) Bleeding Events	The number of participants with adjudicated major or CRNM bleeding events per the Perinatal and Paediatric Haemostasis Subcommittee of International Society on Thrombosis and Haemostasis (ISTH) criteria. Events are adjudicated by a blinded, independent events adjudication committee (EAC).; Major bleeding satisfies one or more of the following criteria: fatal bleeding, clinically overt bleeding associated with a decrease in hemoglobin of at least 20 g/L (i.e., 2 g/dL) in a 24-hour period, bleeding that is retroperitoneal, pulmonary, intracranial, or otherwise involves the CNS, or bleeding that requires surgical intervention in an operating suite, including interventional radiology.; CRNM bleeding satisfies one or both of the following criteria: overt bleeding for which blood product is administered and not directly attributable to the subject's underlying medical condition or bleeding that requires medical or surgical intervention to restore hemostasis, other than in an operating room.	From first dose to 2 days after last dose (Up to approximately 12 months)
Secondary	The Number of Participants With Thrombotic Events and Thromboembolic Event-Related Death	The number of participants with thromboembolic events (intra-cardiac, shunt, inside Fontan pathway, pulmonary embolism (PE), stroke, other arterial or venous thromboembolic events, etc.) and thromboembolic event-related death detected by imaging or clinical diagnosis.; Death and thromboembolic events are adjudicated by a blinded, independent events adjudication committee (EAC)	From randomization to 2 days after last dose (Up to approximately 12 months)
Secondary	The Number of Participants With Adjudicated Major Bleeding	The number of participants with adjudicated major bleeding events per the Perinatal and Paediatric Haemostasis Subcommittee of International Society on Thrombosis and Haemostasis (ISTH) criteria. Major bleeding events are adjudicated by a blinded, independent events adjudication committee (EAC).; Major bleeding is defined as bleeding that satisfies one or more of the following criteria: fatal bleeding; clinically overt bleeding associated with a decrease in hemoglobin of at least 20 g/L (i.e., 2 g/dL) in a 24-hour period; bleeding that is retroperitoneal, pulmonary, intracranial, or otherwise involves the CNS; bleeding that requires surgical intervention in an operating suite, including interventional radiology	From first dose to 2 days after last dose (Up to approximately 12 months)
Secondary	The Number of Participants With Adjudicated CRNM Bleeding	The number of participants with adjudicated clinically relevant non-major (CRNM) bleeding events per the Perinatal and Paediatric Haemostasis Subcommittee of International Society on Thrombosis and Haemostasis (ISTH) criteria. CRNM bleeding events are adjudicated by a blinded, independent events adjudication committee (EAC).; CRNM bleeding is defined as bleeding that satisfies one or both of the following criteria: overt bleeding for which blood product is administered and not directly attributable to the subject's underlying medical condition; bleeding that requires medical or surgical intervention to restore hemostasis, other than in an operating room	From first dose to 2 days after last dose (Up to approximately 12 months)

Secondary	Time of Maximum Observed Concentration (Tmax)		From first dose up to 6 months after first dose
Secondary	Anti-FXa Activity	Anti-FXa Activity was measured to assess participant plasma apixaban levels.; 125 participants received at least one dose of apixaban and had anti-FXa samples collected that contributed measurements to at least one of the timepoints below.	From first dose up to 6 months after first dose
Secondary	Chromogenic FX Assay (Apparent FX Level)	Chromogenic FX was measured to assess (apparent) FX levels in participants and inhibition of FXa by apixaban.; 125 participants received at least one dose of apixaban and had chromogenic FX assay samples collected that contributed measurements to at least one of the timepoints below.	From first dose up to 6 months after first dose
Secondary	The Child and Parent Reports of Pediatric Quality of Life Inventory (PedsQL)	Subjects' quality of life was measured using the PedsQL instrument administered only to English-speaking children/parents. Only subjects who completed the questionnaires at both baseline and post-baseline visits were included in the analyses.; PedsQL consists of 23 items scored on a 5-point Likert scale from 0 (never) to 4 (almost always) or for the child report for younger children ages 5-7, a 3-point Likert scale: 0 (Not at all), 2 (Sometimes), and 4 (A lot).; Scores are reverse scored and transformed to a 0-100 scale as follows: 0=100, 1=75, 3=25, 4=0. Higher scores indicate a better HRQOL and/or lower problems.	from randomization up to 12 months after randomization
Secondary	Kids Informed Decrease Complications Learning on Thrombosis (KIDCLOT) IMPACT Score	Subjects' quality of life was measured using the KIDCLOT instrument administered only to English-speaking children/parents. Only subjects who completed the questionnaires at both baseline and post-baseline visits were included in the analyses.; KIDCLOT Parent inventory uses a 5 point Likert scale from 1 (N/A), 2 (Never), 3 (Rarely), 4 ( Now and then), 5 (Often). Child inventory uses a 4 point Likert scale 1 (N/A), 2 (Never), 3 (Now and then), 5 (Always). Values are scores as follows 1=0, 2=1, 3=2, 4=3, 5=4. Score interpretation is 0 to 100 percent IMPACT of anticoagulation on a child's life therefore, higher scores indicates a more negative effect.	from randomization up to 12 months after randomization
