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.

Abstract

aimsTo assess if there is a difference in the oncogenic risk between GLP-1 RA and comparators in randomized controlled trials. MATERIALS AND

methodsA meta-analysis of randomized controlled trials comparing GLP-1RA to any comparators for diabetes and/or obesity, lasting at least 52 weeks. The endpoints included the incidence of overall cancers and single malignancies.

resultsFifty trials were included. GLP-1RA treatment was not associated with a significant difference in risk for overall cancer (MH-OR 1.05, 95% confidence interval [CI] [0.98, 1.13]). Uterine cancer was significantly reduced in the GLP-1RA arm in trials performed in subjects with obesity (MH-OR 0.24, 95% CI [0.06, 0.94]), but not in those aimed at diabetes treatment (MH-OR 0.92, [0.58, 1.47]). We detected an increase in the risk for thyroid cancer (MH-OR 1.55, [1.05, 2.27]), more evident in longer-term trials, and in the risk for colorectal cancer (MH-OR 1.27 [1.03, 1.57]), which, conversely, was significant only in shorter-term trials. No significant difference in the risk was detected for any other cancer.

conclusionsGLP-1 RA do not appear to produce an effect on most malignancies in clinical trials. A reduction of very close obesity-associated cancers seems possible, whereas a risk signal for thyroid cancer was observed, prompting the need for further specific studies. On the other hand, the small increase observed in colorectal cancer in shorter-term trials may be the effect of a disproportionate increase in diagnostic procedures in the GLP-1 RA arm, because of the suspicion raised by common side effects of GLP-1 RA.
