X-tile analyses stratified by the optimal HDL-C cut-off value at baseline and fluctuation. The X-tile plots in the left panels show the χ2 log-rank values, which represent all possible divisions of the lipid levels into low or high. The X-axis represents a low population, while the Y-axis represents a high population. The optimal cut-off values are highlighted by the black circles in the left panels and are shown in the histograms (the middle panels) and Kaplan–Meier plots (the right panels). A The optimal cut-off value for baseline HDL-C was 1.52 mmol/L. B The optimal cut-off value for HDL-C fluctuation was 0.32 mmol/L
