Age affects drug survival rates of interleukin (IL)‐17 and IL‐23 inhibitors in patients with plaque psoriasis: Results from a retrospective, multicentric, multi‐country, cohort study

However, in stratified analyses conducted in elderly patients, IL-23 inhibitors showed higher drug survival rates than IL-17 inhibitors.
