This table shows the relative change in the BKT scores in P1 and P2 based on the Pre score. There was main effect of group (F (4, 28) = 3.792, p = 0.014). Among groups, VR1 (p < 0.001, d = 3.09) and VR3 (p < 0.001, d = 2.16) showed higher rates than the Control. There was main effect of sessions (F (2, 14) = 176.935 p < 0.001). The two-way interaction between groups and sessions was not significant (F (8, 56) = 1.863, p = 0.084)
