Fig. 3— Kaplan–Meier probability of overall survival in anaemic (——) and nonanaemic patients (·······). The number of anaemic and nonanaemic patients at baseline was 116 and 561, respectively. During follow-up, the predicted number of anaemic patients was 99, 75, 53, 49, 31 and 20 at 10, 20, 30, 40, 50 and 60 months, respectively. During follow-up, the predicted number of nonanaemic patients was 528, 397, 292, 217, 150 and 101 at 10, 20, 30, 40, 50 and 60 months, respectively. #: p = 0.0091.
