Time to disease resolution for chronic and acute ITP cohorts by race. (A) Kaplan-Meier curves are shown demonstrating the time to disease resolution for chronic ITP patients of various races. White, non-Hispanic patients (blue) had the shortest time to disease resolution, followed by Hispanic (green) and black, non-Hispanic patients (purple). No patients classified as “other” had disease resolution. The time to disease resolution was different among groups (P = .006). (B) Kaplan-Meier curves are shown demonstrating the time to disease resolution for acute ITP patients of various races. There was no statistically significant difference in time to disease resolution within these groups (P = .084).
