Scores of VAS (A) and BCS (B) in four groups. VAS scores were significantly decreased while BCS scores were significantly increased in group A at T2-7, group B at T2-5, and group C at T2-3, relative to the corresponding time points in group D (P = 0.041, each). Compared with group C at the corresponding time points, VAS scores were decreased while BCS scores were increased in group A at T4-7, and group B at T4-5 (P = 0.032). Compared with group B, VAS scores were decreased while BCS scores were increased in group A at T6-7 (P = 0.048).
