Risk of adverse perinatal outcomes associated with AKI-D in pregnancy and the postpartum period
| Perinatal outcome, n (%) | AKI-D n=188 | No AKI-D n=1,918,601 | Relative Riska (95% CI) |
|---|---|---|---|
| Low birth weight | 50 (26.6) | 102,958 (5.4) | 4.66 (3.64–5.96) |
| Small for gestational age | 15 (8.0) | 46,080 (2.4) | 3.16 (1.90–5.27) |
| Preterm birth | 61 (32.5) | 242,844 (12.7) | 2.49 (2.03–3.06) |
| Stillbirth | 0 (0.0) | 1416 (0.1) | … |
| Perinatal mortality | ≤5 (≤2.7) | 7320 (0.4) | … |
| Neonatal death | ≤5 (≤2.7) | 15,858 (0.8) | … |
| Any of the above perinatal outcomes | 67 (35.6) | 268,582 (14.0) | 3.40 (2.52–4.58) |
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).

All relative risks are unadjusted, estimated from log-binomial models using generalized estimating equations to account for within-mother clustering from additional pregnancies during follow-up. Ellipses indicate unstable estimates of relative risk due to the low number of events in the AKI-D group.
