Changes in body weight, HbA1c, and insulin dose were expressed as mean differences (MDs) with 95% confidence intervals (CIs). Safety outcomes were assessed using odds ratios (ORs) with 95% CIs.

GLP\u20101RA treatment was associated with a body weight reduction of 4.31\u2009kg (95% CI: 3.61\u20135.00\u2009kg) and a HbA1c reduction of 0.25% (95% CI: 0.18\u20130.32%). Across all studies, insulin dosage was reduced by 9.24\u2009U\/day (95% CI: 7.04\u201311.45\u2009U\/day). Subgroup analysis identified that semaglutide achieved the greatest reductions in all outcome measures. Hypoglycaemic episodes were increased (OR\u2009=\u20091.34; 95% CI: 1.02\u20131.76), while hyperglycaemic episodes decreased (OR: 0.69, 95% CI: 0.56\u20130.87). Gastrointestinal adverse events, including nausea and vomiting, were significantly more frequent with GLP\u20101RA treatment, though no increase in serious adverse events was observed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>GLP\u20101RAs are effective for body weight reduction and glycaemic improvement in individuals with T1D and overweight\/obesity, with acceptable safety profiles.
