<p>SAMM = Severe Acute Maternal Morbidity; NND = Neonatal Deaths; LBW = Low Birth Weight; MCM = Major Congenital Malformations.</p>†<p>For Severe Maternal Morbidity, Low Birth Weight, Prematurity, and Major Congenital Malformations, the median and range of a systematic review is presented for the entire region.
