Table 4. False Positive (Specificity) and False Negative (Sensitivity) of LLRC versus Single Metrics for Velos-Orbitrap^a.

metric	LLRC	P_2C	P_2A	MS1_2B
false positive (specificity)	0.071 (0.929)	0.323 (0.677)	0.386 (0.614)	0.735 (0.265)
false negative (sensitivity)	0.066 (0.934)	0.066 (0.934)	0.066 (0.934)	0.066 (0.934)

^aThe sensitivity is held constant at 0.934 to show the sensitivity for any single metric compared to the LLRC. From Rudnick et al.⁵ P_2C is the total unique tryptic peptide identifications; P_2A is the total spectrum identifications; MS1_2B is the median TIC.
