GLP-1 drugs and pancreatitis in US claims

Glucagonlike peptide 1-based therapies and risk of hospitalization for acute pancreatitis in type 2 diabetes mellitus: a population-based matched case-control study.

Overview

Singh S et al.. JAMA Intern Med 2013 · PMID 23440284 · DOI 10.1001/jamainternmed.2013.2720

Users had about twice the odds of pancreatitis, but they also had more risk factors.

Does the study support the specific claim? Partly · Methodological quality: low

Note: according to the archive, the studies were compiled by the archive operators. Whether Dr. Elawady himself cited this study is not established.

What the archive says about the study

Listed in the archive bibliography for 'oral-diabetes-drugs' without its own interpretation; used as support for the claim that every drug class carries documented harm.

A. What was actually studied?

GLP-1-based therapies and acute pancreatitis

B. What did the authors find?

aOR 2.24.

C. What conclusions do the authors themselves draw?

GLP-1-based therapies associated with increased odds of hospitalisation for acute pancreatitis.

D. What does the archive derive from it?

Support for pancreatitis claim in the archive quote.

E. Is this derivation scientifically justified?

Partly; RCT meta-analysis (I-ODD-11) did not confirm.

Adequacy of the interpretation (by the archive)
