Rosenberg et al developed a simplified age weight score (SAWS) to evaluate mortality in very low birth weight infants in low-resource settings. The authors are from the Johns Hopkins University, the Bangladesh Institute of Child Helath and Kumudini Women's Medical College in Bangladesh.
Patient selection: neonate < 34 weeks of gestation with birthweight <= 1,500 grams
Parameters:
(1) gender
(2) gestational age
(3) body weight at birth in grams
