Risk of hair loss associated with glucagon-like peptide-1 receptor agonists in adults with type 2 diabetes: target trial emulation.

This study included 12 004 GLP-1 receptor agonist initiators and 15 221 SGLT-2 inhibitor initiators in the GLP-1 receptor agonist versus SGLT-2 inhibitor comparison and 11 964 GLP-1 receptor agonist initiators and 11 238 DPP-4 inhibitor initiators in the GLP-1 receptor agonist versus DPP-4 inhibitor comparison.

After stabilised inverse probability of treatment weighting adjustment, use of GLP-1 receptor agonists was associated with a higher risk of alopecia than use of SGLT-2 inhibitors (hazard ratio 1.37, 95% confidence interval 1.08 to 1.73) or DPP-4 inhibitors (1.68, 1.28 to 2.20).
