Multivariable Analyses of Association Between the Relevant Peak Serum Bilirubin Concentration Variable and Potential Confounding Variables, and Blindness Attributable to Retinopathy of Prematurity
| Variables (Units Used to Compute Odds Ratios in Parentheses) | Association With Neurodevelopmental Impairment | |
|---|---|---|
| OR (CI) | P | |
| Peak bilirubin ≥200 μmol/L (20 μmol/L) | 2.89 (1.14–9.53) | .081 |
| pH variable* (per low pH measure) | 1.16 (1.00–1.26) | .074 |
| IVH grades 3 and 4 | 5.38 (1.83–15.84) | .003 |
↵* Total number of pH measurements <7.25 during the period that the serum bilirubin concentration exceeded 100 μmol/L.
