Table 2 Logistic regression analysis of impact of time epoch, gestational age, birth weight, and treated PDA on NEC rates, surgical NEC, and NEC or Death
Data as OR (95% CI) | NEC cases | Surgical NEC | Death or NEC |
|---|---|---|---|
Time epoch (Epoch 1 = Ref) | |||
Epoch 2 | 0.58 (0.30–1.12) | 0.87 (0.34–2.23) | 0.51 (0.28–0.93) |
Epoch 3 | 0.37 (0.20–0.67) | 0.36 (0.14–0.92) | 0.30 (0.18–0.52) |
Gestational age, week | 0.91 (0.74–1.12) | 0.77 (0.57–1.05) | 0.75 (0.63–0.91) |
Birth weight, gram | 1.00 (0.99–1.00) | 0.99 (0.99–1.00) | 0.99 (0.99–1.00) |
PDA treated | 2.17 (1.25–3.76) | 1.23 (0.55–2.74) | 0.83 (0.50–1.38) |
