Figure 2. Risk of maternal and neonatal outcomes with use of different antihypertensive medications in pregnancy.*
*ORs and 95% CIs are calculated after inverse probability of treatment weighting. Labetalol is the referent group. The population for different outcomes differs slightly because pregnancy losses were not included in the denominator for SGA, preterm delivery, or neonatal ICU admission. For most outcomes, the total N is 6346, for SGA the total N is 6240, and for preterm delivery and NICU admission the total N is 6272.
**Weighted prevalence in the subgroup, calculated using inverse probability of treatment weighting with unstabilized weights.
Abbreviations: OR, odds ratio; CI, confidence interval; SGA, small for gestational age; ICU, intensive care unit.
