  • *Statistically significant (p<0.05) differences in baseline characteristics between intervention and control or exposed and unexposed participant groups, as reported by the study authors.

  • †The primary and secondary outcome variables are defined as per the primary studies.

  • ‡Within first 12 hours of treatment initiation.

  • §For all secondary outcome variables, the number or % in exposed vs unexposed groups; attributed to hydrocortisone will be applied for the analysis.

  • BPD, bronchopulmonary dysplasia; DBP, diastolic blood pressure; ICU, intensive care unit; MBP, mean blood pressure; SBP, systolic blood pressure.
