Validation Study of Kim's Sham Needle by Measuring Facial Temperature: An N-of-1 Randomized Double-Blind Placebo-Controlled Clinical Trial

Figure 7

Temperature change before and after treatment with real or sham needle: seven male smokers (A–G) were treated with either a sham needle or a real needle 5 min after smoking and their facial temperature was monitored by DITI. The results show that treatment with a sham needle resulted in an overall decrease in facial temperature, while treatment with a real needle resulted in an overall significant increase in facial temperature in 6 subjects. Values on the graph represent the mean (SD) of 6 independent treatments with 2 h intervals.
