CRP and myocardial ischemia: A non-linear relationship was observed for lymphocyte count (Pnon−linearity < 0.001), CRP (Pnon−linearity = 0.006), LMR (Pnon−linearity < 0.001), and PLR (Pnon−linearity < 0.001) (Supplementary Fig. 1), which showed both lower and higher levels were associated with an increased risk of IHD.
