Low-Dose Glucagon to Prevent and Treat Exercise-Associated Hypoglycemia in Individuals With Type 1 Diabetes: A Systematic Review and Meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivePeople with type 1 diabetes (T1D) struggle to manage exercise because of hypoglycemia risk. RESEARCH DESIGN AND
methodsThis systematic review and meta-analysis evaluated low-dose glucagon's efficacy for preventing and treating exercise-induced hypoglycemia in T1D. Medline, Embase, and Cochrane CENTRAL were searched for randomized controlled trials and crossover studies until September 2024. The analysis included T1D adolescents and adults treated with low-dose glucagon versus nonglucagon treatments. Studies with glucagon-like peptides, noninsulin combinations, or uncontrolled exercise settings were excluded. Two authors extracted the data. The methodological quality was assessed with the Risk of Bias-2 tool and Grading of Recommendations Assessment, Development and Evaluations framework. Risk of Bias 2 informed a sensitivity analysis. The meta-analysis employed a random effects model to estimate the pooled treatment effects on hypoglycemia and time below range (TBR) (glucose <3.9 mmol/L), as well as secondary outcomes and adverse effects.
resultsOf 6,792 records, 12 studies involving 248 individuals (mean age: 36 ± 10.5 years) met inclusion criteria. The meta-analysis showed significant reductions in hypoglycemia risk (risk ratio 0.54; 95% CI 0.35, 0.84) and TBR (-3.91 percentage points; 95% CI -6.27, 1.54) with low-dose glucagon. Sensitivity analysis yielded a slightly more confident effect size for hypoglycemia and TBR. However, overall adverse events increased with low-dose glucagon (risk ratio 2.75; 95% CI 1.07, 7.08). The included studies were few and heterogeneous, which may have influenced the overall outcomes.
conclusionsLow-dose glucagon reduces exercise-induced hypoglycemia and TBR in T1D individuals. Future research should optimize glucagon dosage and timing for various exercise types and durations to confirm real-world effectiveness.
