Community-based Diet & Exercise Program for Knee Pain In Obese/Overweight Osteoarthritis Patients .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Effect of Diet and Exercise on Knee Pain in Patients With Osteoarthritis and Overweight or Obesity: A Randomized Clinical Trial
JAMA. 2022 Dec 13;328(22):2242-2251.Eight hundred and twenty-three (n=823) overweight/obese knee osteoarthritis patients ≥50 years or older were randomized to receive an 18-month diet & exercise program (n=414) or an attention control (n=409), delivered in a community-based setting. The primary outcome of interest was the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) pain score. Secondary outcomes of interest included body weight, waist circumference, WOMAC function, 6-minute walk test, pain medication use, and Short-Form 36 (SF-36) physical and mental subscores. All outcomes were assessed upon completion of the 18-month study. Results of this study found diet & exercise to result in a higher rate of clinically meaningful WOMAC pain score reduction vs. control. Body weight, waist circumference, WOMAC function score, 6-minute walk test, and SF-36 physical subscores were also superior in the diet & exercise group,
