Pooled effects were estimated for fasting plasma glucose (FPG) and glycated hemoglobin (HbA1c) using random-effects models. A subgroup analysis compared probiotics with placebo. An exploratory computational analysis examined the interaction of BBR with \u03b1-glucosidase.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec004\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>More than 30 trials involving over 2,000 participants were included.

Probiotics alone also reduced FPG (approximately \u22120.80 mmol\u00b7L\u2009\u207b\u2009\u00b9) and HbA1c (approximately \u22120.21%) compared with placebo.
