Among White pregnancies, the interaction between sex and group was significant early in gestation (weeks 24–26) with males having lower odds of death in PAH pregnancies, but higher odds of death in control pregnancies, counter to our prediction ( Fig 5 ; S4 Table ); in Black pregnancies, this interaction was significant in week 24, but marginally non-significant in weeks 25 and 26 (P = 0.08 and P = 0.06, respectively; S5 Table ).
