Effects of ethnicity, delivery mode, breastfeeding status and maternal education on the infant gut microbiota over time. A. Canonical correspondence analysis (CCA) ordination biplots illustrating the individual effects of ethnicity, delivery mode, breastfeeding status and maternal education on the variation of infant gut microbiota at four time points (3M, 6M, 12M, and 24M) without adjustment for covariates. B-E. Partial CCA ordination biplots illustrating the independent effects of ethnicity (b), delivery mode (c), breastfeeding status (d) and maternal education (e) on infant gut microbiota after adjusting for the covariates. B-E: At 3M, ethnicity, delivery mode, and breastfeeding status were all used as covariates and adjusted mutually; From 6 M to 24 M, only ethnicity and delivery mode were regarded as covariates and adjusted mutually. The significance of the effects of the environmental variable was tested using the Monte-Carlo Permutation Procedure (MCPP) on each environmental variable.
