When the measure of RDW ≥ 15.7% [ 19 ] was added to the analysis hypochromic erythrocytes remained significant for TTCW (p = 0.011) together with low hemoglobin (p = 0.006), for survival at baseline low hemoglobin (p = 0.029) and RDW ≥ 15.7% (p = 0.011) were the strongest predictors, while for survival at one year hypochromic erythrocytes continued to be the only and highly significant predictor (p < 0.001).
