01 · The sentence it was drawn from

“The model indicated that ginger significantly decreased FBS (MD = −16.27 mg/dL, 95% CI (−25.75, −6.80), I2 = 86.39%, τ2 = 158.79, and Cochran’s Q: 66.11), HbA1c (MD = −0.41%, 95% CI (−0.63, −0.20), I2 = 92.09%, τ2 = 0.06, and Cochran’s Q: 113.8), but its effects on HOMAIR did not reach the threshold of statistical significance (MD = −0.37%, 95% CI (−0.78, 0.03), I2 = 76.35%, τ2 = 0.13, and Cochran’s Q: 21.14).”
