Impact of timing. Kaplan-Meier curve of patients with melanoma brain metastases (MBM) who received radiation therapy (RT) and immunotherapy (n=17) stratified according to immunotherapy timing (immunotherapy before and after RT (ICI→RT) (cyan line, n=6) versus after RT (RT→ICI) (red line, n=11) (Table 1, Source file for Table 1). Hazard ratio (HR) based on Cox proportionality hazard models\ are reported as for ICI→RT vs RT→ICI group 3.54 (0.86–14.65), type 3 p-value = 0.0808, log rank p-value = 0.064.
