X-tile plot of CEA (a), FARI (b), and PNI (c). The x-axis of the X-tile plot represented all possible cut-off values for the marker, with the size of the cut-off values increasing from left to right.

Red colouration indicated an indirect association between markers and prognosis, in which green colouration indicated a direct association between markers and prognosis
