Table 11 KPS 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
Day 1 70.00 ± 15.19 72.86 ± 13.83 67.14 ± 9.14 0.51
Day 2 70.00 ± 15.19 72.86 ± 13.83 67.14 ± 9.14 0.51
Day 3 70.00 ± 15.19 73.57 ± 13.36 67.86 ± 9.75 0.51
Day 4 70.00 ± 15.19 73.57 ± 13.36 68.57 ± 9.49 0.57
Day 5 70.71 ± 14.92 73.57 ± 13.36 68.57 ± 9.49 0.59
Day 6 70.71 ± 14.92 73.57 ± 13.36 68.57 ± 9.49 0.59
Day 7 70.71 ± 14.92 73.57 ± 13.36 68.57 ± 9.49 0.59
Main effect of time (P-value)* <0.05  
  1. *There was no interaction between the changing trends of the KPS scores and the three groups’ intervention factors over time
