Table 3. Comparison of VAS scores between the 2 groups ( $\bar{x} \pm s$ ).

Group	2 h after operation	8 h after operation	12 h after operation	24 h after operation
Observation group (n=58)	1.25±0.30	2.49±0.52	2.21±0.35	1.15±0.12
Control group (n=57)	2.30±0.64	3.05±0.77	2.75±0.60	2.04±0.30
F	F_interblock=16.710, F_{differenttimepoints}=643.500, F_interaction=10.250
P	<0.001

P value, probability; F value, oscillator strength.
