Comparison of the mean temperature change by needle thickness for heated-needle acupuncture (HA). Temperature changes were obtained as the mean of the difference between the maximum and baseline temperatures. A significant difference (P < 0.01) compared to the 0.30 × 40 mm needle; a significant difference (P < 0.01) compared to the 0.40 × 40 mm needle.
