Kaplan-Meier survival curves according to reticulocyte count quartiles at 1 year prior to enrollment. Patients were divided into quartiles according to their reticulocyte count: pQ1, ≤31.5 × 103 cells/μL; pQ2, 31.5 × 103 cells/μL to 42.1 × 103 cells/μL; pQ3, 42.2 × 103 cells/μL to 54.2 × 103 cells/μL; and pQ4, ≥54.4 × 103 cells/μL. a Overall survival; p = 0.02 as determined by a log-rank test conducted to compare the four groups. b Patients who had not died from cardiovascular causes; p = 0.02 according to a log-rank test conducted to compare the four groups
