Characteristics of the Study Population (Intention-to-Treat Population)
Knee Injury, Disability, Osteoarthritis, PROM
OSTEOARTHRITIS
Abbreviations: BMI, body mass index (calculated as weight in kilograms divided by height in meters squared); EQ-5D-5L, European Quality of Life 5-Dimension 5-Level version; EQ-VAS, European Quality of Life Visual Analogue Scale; HOOS-PS, Hip Disability and Osteoarthritis Outcome Score–Physical Function Shortform; KOOS-PS, Knee Injury and Osteoarthritis Outcome Score–Physical Function Shortform; PROM, patient-reported outcome measure; PROMIS, Patient-Reported Outcomes Measurement Information System.PROM scores have different score ranges: −0.661 to 1.0 for the EQ-5D-5L, 0 to 100 for the EQ-VAS, 0 to 100 for the HOOS-PS and KOOS-PS, 33.7 to 75.8 for the PROMIS-fatigue, and 41 to 79.4 for the PROMIS-depression. Higher values on the EQ-VAS and EQ-5D-5L indicate better health levels, whereas lower values on the HOOS-PS, KOOS-PS, PROMIS-fatigue, and PROMIS-depression indicate better health (less health impairment). Due to the low score range of the EQ-5D-5L, 3 digits after the decimal point are reported.
