(A) The acupoints involved in this study. (B) Schematic diagram showing the supplementation and draining manipulations. We defined supplementation as the angle of needle insertion to skin as 45 degrees with the needle tip in the same direction as the meridian. In contrast, draining is defined as the angle of needle insertion at 45 degrees with the needle tip direction opposite to that of the meridian.
