After matching RVMR patients by age and diagnosis to the LVMR patients, 152 pairs were detected

aWexner score for faecal incontinence (minimum–maximum; 0–20)
bValues are reported as medians with 25th and 75th percentiles
cValues are reported as counts and percentiles
dVAS: visual analogue scale (no discomfort–great discomfort; 0–100)
eODS: obstructed defecation symptom score (minimum–maximum; 0–40)
f VAS: visual analogue scale (much worse–much better; 0–100)
