Figure 6 Box plot reporting statistically significant different butyric acid contents at the end of the Khorasan-wheat-diet first arm. Analyses were assessed using the paired Wilcoxon signed-rank test and P values less than 0.05 were considered statistically significant. ^aP < 0.05, ^bP < 0.01, ^cP < 0.001. KDT₀: Pre-Khorasan-wheat-diet first arm; KDT₁: Post-Khorasan-wheat-diet first arm.
