Table 4. Predictive values of lipid panels at the training and the validation stage.

Stage	Sample size	Sens	Spec	PPV(%)	NPV(%)	AUC	OR(95% CI)	Power
Training	105 vs. 80	0.819	0.707	79.63	73.61	0.823	10.9(5.4 −22.0)	0.982
Validation	94 vs. 67	0.787	0.694	77.08	71.43	0.808	8.4(4.2-17.0)	0.971

The predictive values of four lipid species were analyzed between NSCLC vs control. Sens., sensitivity; Spec., specificity; PPV, positive predictive value; NPV, negative predictive value; OR, odds ratio; AUC, area under the curve.
