Figure 3 Diagnostic accuracy and interobserver agreement by experience level. A: Diagnostic accuracy of different experience level and pathology subtype across reading rounds. Significance vs junior group: ^bP < 0.01, ^cP < 0.001; B: Interobserver agreement by experience level across reading rounds. Reference lines: κ = 0 (dashed), κ = 0.2/0.4 (dotted). ^aNegative values indicate agreement worse than chance. SSL: Sessile serrated lesion; SSL-D: Sessile serrated lesion with dysplasia.
