1 · What the graph read from it

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.

2 · The registry

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

Background: To quantify the extent of metabolic and cardiovascular rebound following the discontinuation of GLP-1 receptor agonist (GLP-1RA) therapy in adults with obesity, type 2 diabetes, or type 1 diabetes, and identify potential modifiers of these outcomes. Methods: We conducted a systematic review and meta-analysis of randomized controlled trials including adults and adolescents treated with GLP-1RAs, followed by a post-discontinuation follow-up of at least 12 weeks. Databases searched included MEDLINE, Embase, Cochrane CENTRAL, Web of Science, and ClinicalTrials.gov, with no language restrictions, and published up to October 17, 2025. We assessed changes in anthropometric, glycemic, cardiovascular, and lipid parameters between the end of treatment and the post-cessation period. Random-effects models were used to calculate pooled mean differences. The risk of bias and certainty of evidence were evaluated using the Cochrane ROB 2.0 and GRADE frameworks. The study was registered with PROSPERO under CRD42025646185. Findings: Eighteen RCTs (3771 participants) were included. Among individuals with obesity, discontinuation of GLP-1RA resulted in significant metabolic rebound, characterized by a body weight gain of 5.63 kg (95% CI: 3.52-7.73, I2 = 99.57%, moderate) and an increase in HbA1c of 0.25% (95% CI: 0.18-0.32, I Interpretation: The magnitude and consistency of these effects underscore the physiological consequences of GLP-1RA discontinuation. As the clinical use of GLP-1RAs continues to grow in the management of obesity and diabetes, it is imperative that treatment guidelines address not only initiation and titration but also discontinuation and long-term maintenance strategies to sustain therapeutic gains. Funding: This study received no funding.
