Multivariable analysis: independent risk factors for in-hospital mortality following neonatal cardiac surgery in a LMIC setting
| Risk factors | OR (95% CI) | P value |
| 100 g decrease in birth weight | 1.12 (1.03 to 1.22) | 0.009 |
| Palliative surgery | 4.46 (1.91 to 10.44) | 0.001 |
| Day increase in age | 0.93 (0.87 to 0.99) | 0.02 |
Birth weight, surgery type, age, admission epoch and non-cardiac anomaly were considered for regression analysis.
