Diagnostic performances of MPV, MPV/PC, NLR and PLR for distinguishing colorectal cancer from an adenomatous polyp

Marker	sensitivity	specificity	PPV	NPV	AUC (95% CI)
MPV	96.97	33.33	50.8	93.9	0.607(0.551–0.661)
MPV/PC	89.39	52.15	57.0	87.4	0.739(0.687–0.787)
NLR	72.73	44.62	48.2	69.7	0.579 (0.523–0.634)
PLR	89.39	37.63	50.4	83.3	0.654 (0.599–0.706)
