INS and Insulin resistance: From 13 randomized controlled trials involving 896 patients, individuals with probiotic had significant reduction on homeostasis model assessment insulin resistance (mean difference, −0.72; 95% confidence interval, −1.07 to −0.38; I2, 96%; P=.00), fasting blood glucose level (mean difference, −3.79; 95% confidence interval, −6.24 to −1.34; I2, 93%; P=.00), and insulin level (mean difference, −2.43 mg/dL; 95% confidence interval, −3.37 to −1.48; I2, 54%; P=.00).
