Figure 3

Comparison of NRS scores. Note: The abscissa represents the time points of T0, T1, T2, and T3, and the ordinate represents the NRS score, points. The NRS scores of patients in the experimental group at T0, T1, T2, and T3 were (8.79 ± 1.14), (7.01 ± 0.75), (3.71 ± 0.42), and (1.02 ± 0.11) points, respectively. The NRS scores of patients in the control group at T0, T1, T2, and T3 were (8.78 ± 1.15), (7.11 ± 0.89), (5.88 ± 0.66), and (3.57 ± 0.52) points, respectively. indicates that there is a significant difference in the NRS score at T2 between the two groups of patients (t = 18.608, ). indicates that there is a significant difference in the NRS score at T3 between the two groups (t = 32.184, ).
