*Children with G. intestinalis and other pathogenic and commensal species
**Children with Cryptosporidium spp. and other pathogenic and commensal species
^aMedian (25–75% inter-quantiles); remaining data are presented as mean ± standard deviation
^bWilcoxon rank-sum test
^cANCOVA adjusted by other pathogenic genera or species rather than *G. intestinalis or **Cryptosporidium spp.
^dNot all W/A Z scores of the children could be estimated
