Data are presented as n, n (%) or median (interquartile range), unless otherwise stated. #: serious infection coded as underlying or contributing cause of death on the death certificate (data from the Cause of Death Register); ¶: within-individual hazard ratio estimated from a Cox proportional hazards model with a γ-frailty term (per individual; a shared frailty model). Adjusted hazard ratio estimated using inverse probability of sarcoidosis weights.
