Forest plot with overall survival in subgroups. An adjusted Cox model was used to estimate the hazard ratios for the risk of death from any cause in stage III melanoma patients diagnosed before (precohort) or after (postcohort) July 2018 (based on the timepoint when adjuvant treatment was introduced in Sweden). Patients were grouped depending on age (adjusted for sex and American Joint Committee on Cancer staging system, eighth edition [AJCC-8 stage], sex [adjusted for age and AJCC-8 stage] or tumor staging characteristics [adjusted for age and sex]). HR = hazard ratio.
