Table 9 Functional scale score and changes in the three study arms \( \left(\overline{x}\pm SD\right) \)

From: A pilot randomized controlled trial of acupuncture at the Si Guan Xue for cancer pain

Time Arm 1 (n = 14) Control arm (n = 14) Arm 2 (n = 14) P-value
Baseline 90.29 ± 4.00# 87.24 ± 3.89 88.60 ± 3.56 0.12
Day 7 91.56 ± 4.94 89.21 ± 4.16 90.35 ± 4.10 0.38
Follow up 90.79 ± 4.85 89.78 ± 3.53 90.48 ± 4.27 0.81
Main effect of time (P-value)* <0.05  
  1. *There was no interaction between the changing trends of Functional scale scores and the three groups’ intervention factors over time
