A total of 93 MR patients with a median (IQR) age of 59.00 (50.50-65.00) were recruited for the study, of whom 38 (40.9%) were female. Of the 93 patients, 29 (31.2%), 29 (31.2%), and 35 (37.6%) were classified into mild, moderate, and severe MR, respectively. All variables were non-normally distributed; thus, the nonparametric tests were utilized.
