Effects of soil-transmitted helminth infection status on changes in physical fitness and strength indicators (primary outcomes) at various follow-ups from baseline among 194 children from south-west Yunnan province, P.R. China, who participated in the randomized controlled trial conducted from October 2011 to May 2012.

a<p>For each model, the outcome variable is highlighted with a grey bar and the explanatory variables (reference group is always not infected with the particular soil-transmitted helminth species) are presented below. All models have been adjusted for village, and at the individual level for sex, age at follow-up, and height and weight at baseline (for the 1-month follow-up) or follow-up (for the 4- and 6-month follow-ups). Values are presented as coefficient (95% confidence interval) and highlighted in bold if statistical significance is achieved (<i>P</i><0.05).</p
