Table 3:
Length of Stay and Breast Milk Feeding by Intervention versus Control Group
| Exploratory Outcome | Intervention | Control | Effect Size |
|---|---|---|---|
| Breast Milk Feeding at Discharge, % | Mean (95% CI) | Percentage Point Difference (95% CI) | |
| Any Breast Milk | 88.5 (79.8 – 97.1) | 78.6 (63.4 – 93.8) | 9.9 (−7.6 – 27.4) a |
| Exclusive Breast Milk | 30.8 (18.2 – 43.3) | 10.7 (−0.7 – 22.2) | 20.0 (3.1 – 37.0) a |
| Median (IQR) | C-statistic (95% CI) | ||
| Length of Stay, days | 12 (5.5 – 29) | 20 (13.5 – 30.5) | 0.62 (0.496 – 0.75) b |
CI – confidence interval. IQR – interquartile range.
a
Wald CI for the difference in proportion.
b
The point and CI for the C-statistic was calculated by transforming the corresponding Somers’ D point and interval estimates using the transformation C=0.5(D+1).
