Notes. All statistically significant coefficients are marked in bold.
aAll mean VO2 max estimates are expressed in ml kg-1 min-1 and are adjusted for age.
bAll mean grip strength values are expressed in kg and are not adjusted for age.
cAll p-values are calculated using either mixed linear or mixed logistic regression, adjusted for clustering within school classes.
dInfected with one or two soil-transmitted helminth species (A. lumbricoides and/or T. trichiura).
eStunted: is defined as <-2 HAZ.
