BMI: body mass index; CSBM: complete spontaneous bowel movement; PAC-QOL: patient assessment of constipation quality of life. Data are expressed as no. of participants (%) unless otherwise indicated; 24 participants missed the 1 wk defecation diaries but completed all other defecation diaries (9 in the EA group and 15 in the SA group). A threshold of P<0.25 was used to select variables [10].
