Most registries with higher CFR also had higher BPR. Differences were attributable to type of registry (hospital-based vs. population-based), ETOPFA (allowed yes or no) and geographical regions. These findings contribute to the understanding of regional differences of CH occurrence and early neonatal deaths.enMedicineCase fatality ratePoisson regressionConfidence intervalPediatricsPregnancyObstetricsreview
