Fig. 6. Change of quality of life ([A] short form-8 [SF-8] and the [B] Japanese version of the patient assessment of constipation quality of life [JPACQOL]) in Japanese patients with chronic constipation. The 2 groups also showed no differences in physical component summary (PCS) score and mental component summary (MCS) score. JPAC-QOL evaluations indicated that the degree of change in the total score before versus after the intervention was significantly higher in the magnesium oxide (MgO) group than in the placebo group.
