|Predefined hypotheses and the confirmation or rejection of the hypotheses for hip OA (n = 117) and knee OA (n = 284)|
|Hip OA||Knee OA|
|There is a moderate correlation (r > 0.6) between LEFS scores and HOOS/KOOS-PF subscale.||Yes||Yes|
|The correlation between the LEFS and the HOOS/KOOS-PF subscale is higher than the correlation between the LEFS and the other subscales of the HOOS/KOOS.||Yes||Yes|
|The correlation between LEFS and HADS scores is low (r < 0.5).||Yes||Yes|
|The correlation between LEFS and CIS scores is low (r < 0.5).||No||Yes|
|Patients with multiple painful lower limb joints demonstrate lower LEFS scores than patients with pain in a single joint.||Yes||Yes|
|Patients with complaints less than 5 years demonstrate higher LEFS scores than patients with complaints over 5 years.||Yes||No|
|The participants’ education level (primary, secondary or higher education) does not influence the LEFS scores.||Yes||No|
|Sociodemographic characteristics, such as sex, doing volunteer work, income, type of health insurance, and family status, are unrelated (r < 0.2) to the LEFS score:||Yes||Yes|
|7/8 (88%)||6/8 (75%)|
Abbreviations: CIS = Checklist Individuals Strength, HADS = Hospital Anxiety and Depression Questionnaire, HOOS = Hip Osteoarthritis and Outcome Score, KOOS = Knee Osteoarthritis and Outcome Score, LEFS = Lower Extremity Functional Scale, OA = osteoarthritis, PF = physical function.
