Study to Study Comparisons: Sensitivity Analysis of Basic Elements

Studies	Basic Elements Common to AH and Rehab n/N (%)	AH Unique n/N (%)	Rehab Unique n/N (%)
CENTER-TRACK	31/35 (89%)	10/11 (91%)	10/15 (67%)
CENTER-ADAPT	23/27 (85%)	8/11 (73%)	2/12 (17%)
TRACK-ADAPT	24/27 (89%	9/11 (82%)	4/12 (33%)

n/N (%): n harmonized/N harmonizable.

Eight basic elements common to “AH” and “Rehab” are not applicable to ADAPT (see Supplementary Table S2) as they are not relevant to the study population of pediatric patients with severe TBI. Three elements unique to Rehab are not applicable to ADAPT (see Supplementary Table S2) as they are not relevant to the study population of pediatric patients with severe TBI. These concern “marital status,” “SWLS,” and the “CHART-SF.”

AH, Acute Hospitalized; CENTER-TBI, Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury; TRACK-TBI, Transforming Research and Clinical Knowledge in Traumatic Brain Injury; ADAPT, Approaches and Decisions in Acute Pediatric Traumatic Brain Injury; SWLS, Satisfaction with Life Scale; CHART-SF, Craig Handicap Assessment Reporting Technique Short Form.
