Table 9. Correlation between the two schemes and the specialist group (S1–S5) and the resident group (R1–R5) in the external validation set for patient-level classification.

	Plain scheme	Trinary scheme
S1	0.39	0.61
S2	0.35	0.63
S3	0.26	0.48
S4	0.11	0.33
S5	0.09	0.42

R2	0.33	0.44
R3	0.03	0.50
R4	0.19	0.31
