Rates of recurrent malignancy, and risk of early and late recurrent malignancy according to GVHD condition. (A) Relapse rates were calculated within sequential 90-day intervals for patients without GVHD shown in green, for patients with grades II-IV GVHD without chronic GVHD shown in blue, and for patients with NIH chronic GVHD shown in red. Small symbols represent the actual relapse rates for each 90-day interval. The smoothed rates were plotted as curves for each condition. Low event rates account for large variations between sequential intervals after 36 months. (B-C) Risk of early and late recurrent malignancy according to GVHD condition. *Number of patients at risk in the condition at any time during the period of analysis. †Hazard ratios were adjusted for disease, risk category, and total body irradiation.
