GLP1R and bullous pemphigoid: Cox regression estimated hazard ratios (HRs) and 95% confidence intervals (CIs).<h4>Results</h4>Compared with DPP-4i initiation, GLP-1 RA initiation was associated with a higher risk of incident psoriasis (HR 1.19, 95% CI 1.11-1.28) and lower risks of pemphigus (HR 0.32, 95% CI 0.16-0.63) and bullous pemphigoid (HR 0.61, 95% CI 0.43-0.87).
