Fig. 5
Correlation between BMI-related differences in intestinal flora and immune-related genes. A Heat map of correlation between the dominant flora and checkpoints in the Normal weight group. B Heat map of the correlation between the dominant flora and chemokines in the Normal weight group. C Heat map of correlation between the dominant flora and checkpoints in the Overweight group. D Heat map of the correlation between the dominant flora and chemokines in the Overweight group. In the figure, the horizontal coordinate is the immune-related genes, and the vertical coordinate is the bacteria. In the figure, the red indicates the positive correlation, and the blue indicates the negative correlation. The color depth indicates the size of the Pearson correlation coefficient, and the color from light to dark indicates the value of the phase relationship from small to large. The “*” in the graph represents the size of the P-value: No * for P-value ≥ 0.05, * for 0.01 ≤ P < 0.05, ** for 0.001 ≤ P < 0.01, *** for P < 0.001
