Figure 4. Comparison of detection time point of human surgeons and SurgSmart towards cystic duct and artery with and without severe inflammation: (A, B) for a low-severity case (Parkland Grade ≤ 2); and (C, D) for a high-severity case (Parkland Grade ≥ 3). *P < 0.05 between trainees/seniors and SurgSmart; **P < 0.01 between trainees/seniors and SurgSmart; ^P < 0.05 between trainees and seniors; ^^P < 0.01 between trainees and seniors. The red reference line stands for the detection time point of SurgSmart.
