Pearson’s Chi-squared test of the blood glucose effect of the dragon blood-treated and control groups. Each week’s blood glucose measurement for a given individual between the experimental and control groups was subtracted from the measurement taken from W0. (A) Each blood glucose measurement was classified into the “low” group if < W0; or into the “high” group if > W0. (B) The Chi-square test results indicated that the dragon blood-treated group is statistically significant (p-value = 2.855e-16 < 0.05), indicating the blood glucose lowering effect was non-random even. The odds ratio of lower blood glucose in the BD group compared to the control group was 31.77
