Cross-sectional associations of low body mass index and being underweight with joint damage in Chinese patients with rheumatoid arthritis.

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
Objective: To characterize BMI in Chinese patients with RA Methods: Each of the 1318 patients from a real-world Chinese RA population was first stratified by gender and then individually age-matched with one American RA patient from the US National Health and Nutritional Examination Survey 1999-2018. Data on BMI, bilateral hand radiographs and risk factors at enrolment were collected but radiographs were unavailable for the American patients. Logistic regression was used to evaluate the association of BMI with radiographic joint damage (RJD) in Chinese patients. Results: Chinese patients had a significantly lower BMI [(weighted) median 21.8 Conclusion: Low BMI and being underweight were cross-sectionally associated with joint damage in Chinese RA patients, especially JSN, suggesting the clinical importance of identifying underweight patients and focusing on weight gain to prevent joint damage.
