Fig. 2From: Effectiveness and safety of Bifidobacterium and berberine in human hyperglycemia and their regulatory effect on the gut microbiota: a multi-center, double-blind, randomized, parallel-controlled studyHeat map showing differentially abundant taxa of the fecal microbiota between baseline and 16 weeks of treatment in four experiments. The values of color in the heat map represent the Z-score. Only bacterial taxa that were significant in one of the experiments were included. The Wilcoxon matched-pairs signed-rank tests were used, *P < 0.05; **P < 0.01Back to article page
