Expected proportions ( $p$ ) of early- and full-term deliveries and of LBW among exposed and unexposed pregnancies in the RCT contrasting no exposure to starting medication at 37 weeks.

Per-protocol	Exposed	Unexposed	Probability LBW
$p$ Early delivery	0	0.18	0.5
$p$ Full term	1	0.82	0.05
$p$ LBW	0.05	0.132
ITT/treatment strategy	Treated group	Control group	Probability LBW
$p$ Early delivery	0.1	0.1	0.5
$p$ Full term	0.9	0.9	0.05
$p$ LBW	0.095	0.095

LBW: low birth weight; RCT: randomized controlled trial; ITT: intent-to-treat.
