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.
