Tumour Risk with Once-Weekly Glucagon-Like Peptide-1 Receptor Agonists in Type 2 Diabetes Mellitus Patients: A Systematic Review.
Synthesis in Clinical drug investigation, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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 AND
objectiveOnce-weekly glucagon-like peptide-1 receptor agonists (GLP-1RAs) are a novel class of injectable antidiabetic drugs. Previous studies indicated that GLP-1RAs (exenatide and liraglutide) might increase the incidence of pancreatitis and pancreatic cancer. Here, we evaluated the clinical safety of once-weekly GLP-1RAs with respect to tumour risk.
methodsRelevant studies were selected from ClinicalTrials.gov. Randomized controlled trials that reported the incidences of neoplasms were included in our research. Outcomes were calculated as the risk ratio using the Mantel-Haenszel method and fixed-effects model.
resultsOur analysis included 26 randomized controlled trials with 16,090 patients. Once-weekly GLP-1RAs did not increase the risk for tumours compared with other antidiabetic drugs [risk ratio (RR), 1.02; 95 % confidence interval (CI), 0.74-1.41; p = 0.91]; this finding was independent of the type of GLP-1RA administered (albiglutide, exenatide extended-release and dulaglutide) and duration of the trials (limited to ≥52 weeks). Subgroup analyses revealed that once-weekly GLP-1RAs did not increase tumour risk compared with placebos, exenatide and liraglutide, insulin or oral drugs. Additionally, once-weekly GLP-1RAs did not increase tumour risk in any tissue.
conclusionsCompared with other antidiabetic drugs, once-weekly GLP-1RAs did not increase the risk for any tumour, and this finding was independent of the type of GLP-1RA administered and treatment duration. However, our study had many limitations, and further longer term trials with larger samples should be conducted in future to confirm our results.
