a
OR, odds ratios obtained from accelerated failure time log-logistic models, adjusted for sex and age (in months); age adjusted for sex only; sex adjusted for age only.
b
Generalized log-rank test using within-subject resampling (not adjusted for sex and age).
c
Window of significantly different shedding quantity (Cryptosporidium DNA copies/g, by qPCR) in days after onset of diarrhea; estimates obtained from generalized additive mixed model difference smooths, adjusted for sex and age (in months); age adjusted for sex only; sex adjusted for age only.
