Eligible trials reported fasting blood glucose, HbA1c, serum insulin, or Homeostasis Model Assessment for Insulin Resistance (HOMA-IR). Secondary outcomes included anthropometrics, lipid profiles, and psychopathology (Positive and Negative Syndrome Scale).

For fasting glucose, topiramate, synbiotic, vitamin E, and probiotic\/selenium were beneficial. Metformin improved insulin levels and HOMA-IR, while aripiprazole showed significant improvement in HbA1c. Secondary outcomes revealed reductions in body mass index and body weight with aripiprazole, liraglutide, metformin, nizatidine, sibutramine, topiramate, zonisamide, and berberine. Lipid improvements were observed with aripiprazole, liraglutide, pioglitazone, pravastatin, sitagliptin, topiramate, berberine, synbiotic, and Withania somnifera.
