¹Examinees’ pain during colonoscopy was assessed after the procedure and scored from 0 to 10 using a face pain scale (0-very happy, no pain, 2-hurts just a little bit, 4-hurts a little more, 6-hurts even more, 8-hurts a lot, 10-hurts as much as you can imagine; don’t have to be crying to feel this much pain). CSP: Conventional single pants; NDP: Novel double pants.
