Group laparoscopic intra-corporeal knot tying (LICK) learning curves. Participants of G1, G2, and G3 performed 69 consecutive repetitions (R0–R68) of the task during phase 1 (P1): R0–R2, phase 2 (P2): none, phase 3 (P3): R3–R62, phase 4 (P4): R63–R 65, and phase 5 (P5): R66–R68. The scores were plotted, and group learning curves were calculated. In all groups, the two-phase exponential decay model was the best fitting model
