Incidence of 90-day maternal mortality and chronic dialysis dependence among pregnancies with and without AKI-D

Maternal outcome, n (%)	AKI-D n=188	No AKI-D n=1,918,601	P Valuea
Maternal mortality	8 (4.3)	229 (0.01)	<0.001
Chronic dialysis dependenceb	7 (3.9)c

To comply with privacy regulations for minimizing the chance of identification of a study participant, numbers of participants are suppressed in the case of five or fewer participants (reported as ≤5).

^aP values represent the difference in unadjusted relative risk of the specified maternal outcome associated with the presence versus absence of AKI-D in pregnancy. This was estimated from log-binomial models using generalized estimating equations to account for within-mother clustering from additional pregnancies during follow-up. Unadjusted relative risks were not reported due to unstable estimates as a result of the low number of events in the group without AKI-D.

^bChronic dialysis dependence was not relevant in the No AKI-D group.

^cRefers to the 180 (95.7%) pregnancies complicated by AKI-D in which the mother survived beyond 90 days.
