Table 3. Performances of physicians without and with support of AI in classification of moderate-severe vs. non-moderate-severe in MR patients.

Physician group	Sensitivity (%) (95% CI)			Specificity (%) (95% CI)
	Without AI	With AI		Without AI	With AI
All physicians (n=9)	77.0 (70.9–82.1)	86.7 (80.3–91.2)		91.5 (87.8–94.1)	90.5 (86.7–93.2)
Junior physicians (n=3)	84.0 (72.6–91.3)	95.8 (94.3–96.9)		87.4 (78.9–92.8)	84.4 (82.2–86.4)
Intermediate physicians (n=3)	77.5 (68.7–84.3)	85.4 (76.1–91.6)		93.1 (89.7–95.4)	91.3 (89.3–93.0)
Senior physicians (n=3)	69.5 (68.7–70.2)	78.9 (74.7–82.5)		93.9 (92.4–95.2)	95.7 (93.4–97.2)
