Prevalence of survival without major morbidity and associated risk factors among very preterm infants: a systematic review and meta-analysis.

ABSTRACT:

Introduction

Survival without major morbidity (SWMM) in very preterm infants represents a critical outcome measure in neonatal care. This systematic review evaluates both the prevalence of SWMM among infants born before 32 weeks' gestation and the associated risk factors.
