Prognostic values of serum CRP-SAA, total SAA, and CRP in the prospective cohort of lung cancer patients. a Kaplan–Meier survival curves of the 222 patients divided by the cutoff OD value for CRP-SAA into low- and high-level groups. b Survival curves of 80 patients at stages I–II divided by the cutoff value for CRP-SAA into low- and high-level groups. c Survival curves of 142 patients at stages III–IV divided by the cutoff value for CRP-SAA into low- and high-level groups. d Survival curves of the 222 patients divided by the cutoff OD value for total SAA into low- and high-level groups. e Survival curves of 80 patients at stages I–II divided by the cutoff value for total SAA into low- and high-level groups. f Survival curves of 142 patients at stages III–IV divided by the cutoff value for total SAA into low- and high-level groups. g Survival curves of the 222 patients divided by the cutoff value for CRP into low- and high-level groups. h Survival curves of 80 patients at stages I–II divided by the cutoff value for CRP into low- and high-level groups. i Survival curves of 142 patients at stages III–IV divided by the cutoff value for CRP into low- and high-level groups.
