As shown in Table 3 , in both models, the main effect of intubation experience remained highly significant (Model 1: F(2, 22) = 31.97, P < 0.001, partial η 2 =0.744; Model 2: F(2, 18) = 57.35, P < 0.001, partial η 2 = 0.864), confirming that procedure-specific experience was the primary determinant of technical performance.
