Factors associated with frailty in Japanese patients with rheumatoid arthritis: results from the Institute of Rheumatology Rheumatoid Arthritis cohort study.
Article in Clinical rheumatology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
This study aimed to evaluate the prevalence of, and the factors associated with, frailty in Japanese patients with rheumatoid arthritis (RA). Patients with RA enrolled in the Institute of Rheumatology Rheumatoid Arthritis (IORRA) cohort completed self-administered questionnaires, which included the 5-item frailty screening index. Patients were classified as frail, prefrail, or robust based on the 5 components of the frailty screening index. Logistic regression analyses were used to evaluate associations between clinical variables and frailty. Among 3,290 Japanese patients with RA (86.7% female, mean age 62.4 years) who participated this frailty study, 549 (16.7%) patients were categorized as frailty, 2,063 (62.7%) as prefrailty, and 678 (20.6%) as robust. In multivariable models, body mass index (BMI) ≥ 25 kg/m
