Structured population data were available for 3 of 3 supporting studies. 3 studies described participants with type 2 diabetes. 3 studies described adult participants.

1 study contains conflicting p-value and significance fields; those significance claims are suppressed.

Placebo Group

Core clinician-reference fields are available or not applicable.

Participants received a multi-strain probiotic formula alongside standard hypoglycemic therapy.

Probiotic Group

Participants in the probiotic group consumed one strip of the probiotic formulation daily for 12 weeks, in addition to standard hypoglycemic therapy.

Participants received a matched placebo strip containing only dextrin.

Participants in the placebo group received one matched strip per day containing only dextrin, identical in appearance, weight, color, and packaging to the probiotic product.

Authoritative quality diagnostic: p value significance conflict.

Probiotic improves metabolic profiles in type 2 diabetes patients

Participants received a multi-strain probiotic supplement daily for 6 months.

A total of 91 adults with T2D (mean age [±SD] 65.12 ± 10.92 years, 62.6% males) were randomized to receive the probiotic supplement (n = 46) compared to the controls (n = 45).

Participants received a matching placebo capsule daily for 6 months.

Participants were randomized to receive the probiotic supplement or a matching placebo capsule, both taken once daily.

Placebo capsule

Participants received one capsule of multi-species probiotic plus 100 mg fructo-oligosaccharide supplement daily for 8 weeks.

Daily synbiotic supplement

In this randomized double-blind placebo controlled clinical trial, 50 patients suffering from T2DM and periodontal disease were recruited and randomly assigned to two groups: intervention group (n = 25), where one capsule of multi-species probiotic plus 100 mg fructo-oligosaccharide supplement (500 mg in each capsule) every day is given.

Participants received one placebo capsule containing 500 mg wheat flour daily for 8 weeks.

and control group (n = 25), which received one placebo capsule containing 500 mg wheat flour for 8 weeks.
