They studied six adolescents with appendicitis and administered acupuncture for pain control prior to surgery. Pain was assessed using three analog scales, and inflammation was measured using serial white blood cell (WBC) counts and C-reactive protein levels (CRP). CRP is a nonspecific indicator of inflammation in the body.
Figure 2 from the paper summarizes the results.
You can see that after 20 minutes of acupuncture, all three pain scores and WBCs declined. However, CRP continued to rise. Conspicuously absent from the figure and the text of the paper are any statistical analyses. This is due to the lack of a significant difference in any of these values because of the limited number of subjects studied.
