Relative abundance of bacterial genera that differed significantly between the responders and non-responders; responders were identified by lower scores of IBS-SSS and/or pain during the low FODMAP rye bread period compared to baseline. The box extends from 25th percentile to 75th percentile, with a line at the median; the whiskers refer to the highest and lowest values. Abundances are plotted for baseline and for both bread periods and those with a statistically significant (adjusted p < 0.05) difference are indicated with an asterisk
