Table 6 Comparison of hyper plastic polyp detection between endoscopists

Parameter	Sensitivity	Specificity	PPV	NPV	PLR
Endoscopist 1	53 (32-73)	83 (66-93)	67 (42-85)	74 (57-85)	3.2 (1.3-7.8)
Endoscopist 2	91 (62-98)	56 (43-69)	29 (17-46)	97 (84-99)	2.1 (1.5-3.0)
Endoscopist 3	87 (62-96)	58 (44-71)	39 (25-56)	93 (79-98)	2.1 (1.4-3.1)
P value for three endoscopists	0.026	0.033	0.049	0.008

PPV: Positive predictive value; NPV: Negative predictive value; PLR: Positive likelihood ratio.
