OS following splenectomy among patients with ITP, stratified by TPO-RA use. Kaplan-Meier curves illustrate OS after splenectomy among patients with ITP who did (green) or did not (red) receive postsplenectomy TPO-RA therapy. No significant difference in OS was observed between groups (P = .7). A total of 12 deaths occurred during the study period (6 deaths in each group). Patients who remained alive were censored at the date of the last follow-up. The number at risk at each time point is shown below the x-axis. OS, overall survival.
