Data are expressed as medians of Japanese yen (interquartile range). Obesity categorized by body mass index (BMI) ≥25 kg/m2. †Differences between subgroups were compared using Mann–Whitney U‐tests for skewed continuous variables. ‡All outpatient services = total medical expenditures – hospitalization costs. §Data were analyzed only in patients that were hospitalized (total 54 patients; 31 without and 23 with obesity).
