Data shown are median values with 25th and 75th percentiles. CCLR cranial cruciate ligament rupture. ^a CCLR and control dogs had identical median values for dog body condition score but the Mann Whitney rank sum (MWRS) test detected a significant difference between the groups, with a higher mean body score for CCLR dogs (2.7) than for control dogs (2.6). The MWRS test compares mean ranks and not median values
