  1. BFW: breast-feeding women, I: infants (0-1 year old), Possibly: some association between helminth infection and stunting may have been found, or a suggestion of benefit with anthelmintic treatment, but no statistically significant association was found. Also applies when a suspected association was found in case reports and case series, as these study designs provide a weaker level of evidence. (Age group category thresholds for children as defined by WHO [16]), PSAC: pre-school age children (1-5 year olds), PW: pregnant women, ROB: risk of bias, SAC: school age children (5+ to 20 year olds), schisto: schistosomes, STH: soil-transmitted helminths
