  • —, not applicable.

  • a Summary statistics are shown as mean (SD) except when specified as dichotomous.

  • b The comparative statistic is the mean difference for continuous outcomes (intervention minus control) and odds ratio for dichotomous outcomes (the risk of receiving the intervention compared with receiving usual care).

  • c Outcome is dichotomous (percentage).
