Univariate and Multivariate Analyses of Primary and Secondary Predictors.
| Analysis | PVS (n = 23) | No PVS (n = 69) | p-Value |
|---|---|---|---|
| Univariate | |||
| Time of exposure to shunt (months) | 6 (4, 16) | 3 (2, 6) | 0.002 |
| Age at primary repair (≥4 months) | 17 (81%) | 29 (42%) | 0.003 |
| Premature (birth ≤ 35 weeks GA) | 11 (48%) | 9 (13%) | 0.003 |
| Multivariate | Odds Ratio | 95% CI | |
| Risk of PVS per month of exposure to shunt | 1.21 | (1.06, 1.39) | 0.007 |
| Premature (birth ≤ 35 weeks GA) | 4.77 | (1.36, 16.8) | 0.015 |
All data is presented at numbers (percentages) or median (interquartile range) for the univariate analysis and odds ratio with 95% confidence intervals for the multivariate analysis. GA: gestational age, CI: confidence interval.
