Congenital diaphragmatic hernia pregnancies complicated by an intrathoracic stomach had higher odds of neonatal mortality when compared with intraabdominal stomach (odds ratio [OR] 2.86; 95% CI 1.38\u20135.94). Four papers with SP grading from level 0 to level 3 were included in a subgroup analysis. Stomach position at level 1 and level 2 had lower odds of neonatal mortality when separately compared to level 3 (OR 0.12; 95% CI 0.04\u20130.33) and (OR 0.30; 95% CI 0.16\u20130.54).
