  1. Alpha diversity comparison between H. pylori negative controls (n = 212) and infected cases (n = 212). Scores are expressed as median (1st–3rd quartile) and mean ± SEM. The statistical significance was assessed using the t-test or Mann-Whitney test (MW) for normally or non-normally distributed scores, respectively. *Indicates a significant test result.
