RDW levels in lung cancer patients according to stage.

<p>(A) RDW levels of lung cancer patients. Kruskal-Wallis test: <i>p</i><0.0001. Tukey non-parametric test: <i>p</i>-value I–II=0.58; I–III=0.039; I–IV<0.001; II–III=0.29; II–IV=0.021; III–IV=0.13. (B) RDW levels of patients with lung cancer without any comorbid disease. Kruskal-Wallis test: <i>p</i><0.0001. Ad hoc, Tukey non-parametric test: <i>p</i>-value I–II=0.96; I–III=0.043; I–IV=<0.0001; II–III=0.13; II–IV<0.0001; III–IV<0.001. The box plots in the figure represent columns of data as boxes whose extents indicate the 25^th and 75^th percentiles. The line inside the box represents the median. Capped bars indicate the minimum and maximum values.</p

Survival rates of lung cancer patients stratified by RDW.

<p>(A) Survival rates for patients with stages I-IV lung cancer (n=332, high RDW (n=73) vs low RDW (n=259)). (B) Survival rate for patients with stages I and II lung cancer (n=141, high RDW (n=19) vs. low RDW (n=122)). (C) Survival rate for patients with stages III and IV lung cancer (n=191, high RDW (n=54) vs. low RDW (n=137)).</p
