Body mass index and health-related quality of life of outpatients with knee osteoarthritis: evidence from a cross-sectional study.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo estimate the health-related quality of life (HRQoL) of knee osteoarthritis outpatients in China overall and by body mass index (BMI), and to explore the factors associated with knee osteoarthritis.
methodThis was a cross-sectional study in which outpatients with knee osteoarthritis were recruited from three tertiary hospitals in China from June 2020 to May 2021. The EuroQoL five-dimensional instrument was used to measure HRQoL. Descriptive analysis, one-way analysis of variance, and a Tobit regression model were performed.
resultsOne thousand and eight questionnaires were distributed, and nine hundred and fifty-two participants were included. The mean age was 61.71 years, and 61.03% of the participants were female. The mean health utility was 0.751 (95% CI 0.737, 0.765). The health utility varied significantly according to BMI: underweight = 0.627 (95% CI 0.536, 0.719), normal = 0.764 (95% CI 0.744, 0.784), overweight = 0.755 (95% CI 0.733, 0.776), and obese = 0.728 (95%CI 0.681, 0.776). Additionally, outpatients with knee osteoarthritis who were younger, had received treatment in the past six months, and had a disease duration shorter than 2 years had significantly higher HRQoL scores.
conclusionThe HRQoL of knee osteoarthritis outpatients was considerably impaired and was significantly associated with BMI. These findings emphasize the importance of weight examination and management in outpatients with knee osteoarthritis for healthcare providers. Supplementary data were provided for public health-related policies and health economics studies, contributing to the development of effective management strategies and increasing the breadth of knowledge of HRQoL in outpatients with knee osteoarthritis.
