Extended Data Fig. 3. Alpha diversity indexes stratified by the three sampling time points (Day 1, Day 15, and Day 85).
The Fisher’s alpha diversity index, the Chao1 estimated richness, and the observed richness were significantly different across the 11 3-month age groups as analysed by the non-parametric Kruskal-Wallis test. Data were tested for normality using the Anderson-Darling and the D’Agostino & Pearson test in Prism 9 for macOS and were non-normally distributed. The Simpson’s index was only significantly different in the day 1 dataset. Data were considered to be statistically significant with a confidence level of 95%. Data were plotted using the Scatter dot plot function in Prism 9 for macOS with a line drawn at the mean with error bars extending to the standard deviation. In the day 1 dataset there were 520 samples, in the day 15 dataset there were 412 samples, in the day 85 dataset there were 457 samples.
