We evaluated the efficacy/effectiveness of community-based interventions to decrease neonatal mortality. A systematic review of randomized controlled trials, cluster randomized trials and cohort studies of interventions on pregnant women, neonates (up to 28 days after birth) or both was made. Thirty four studies were evaluated (n=844,989): 20 in pregnant women (n=406,172), 6 in neonates (n=24,994), and 8 in both (n=413,823).
