Progression-free survival (PFS) (a) and overall survival (OS) (b) in melanoma patients undergoing anti-PD-1 antibodies based on severity of irAE The patients who experienced no irAEs, mild irAEs (grade 1–2), and severe irAEs (grade 3–5) had significantly different PFS (p = 0.001) and OS (p < 0.001). The patients with mild irAEs showed favorable survival and those with severe irAEs showed unfavorable survival. The numbers below the charts correspond to patients at risk at each time point. irAEs, immune-related adverse events
