Increasing fracture incidence over 13 years in patients with rheumatoid arthritis from the IORRA cohort.
Observational study in Journal of bone and mineral metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionThis study aimed to evaluate fracture incidence in patients with rheumatoid arthritis (RA) over 13 years in the Institute of Rheumatology Rheumatoid Arthritis (IORRA) cohort study. MATERIALS AND
methodsThe IORRA is a prospective observational cohort study of Japanese patients with RA. Between 2011 and 2023, 10,257 patients with RA were enrolled. Clinical parameters and data on fractures were collected biannually using self-reported questionnaires. The fracture incidence, standardized by sex, age, and Japanese Health Assessment Questionnaire score, was calculated for each two-year period.
resultsFrom 2011 to 2023, the proportions of patients achieving Disease Activity Score in 28 joints remission, using biologic disease-modifying antirheumatic drugs, and taking osteoporosis medications increased (38.0% to 64.7%, 14.2% to 42.2%, and 31.6% to 38.3%, respectively), while the proportion of glucocorticoid use decreased (38.3% to 22.2%). The incidence of all and non-vertebral fractures increased from 47.2 and 36.7/1000 person-years in 2011 to 52.8 and 43.0/1000 person-years in 2023, respectively. Using 2023 as the reference, the standardized incidence ratios for all and non-vertebral fractures were: 2011-2012, 0.90 [95% confidence interval (CI) 0.82-0.98] and 0.86 (95% CI 0.78-0.95); 2013-2014, 0.88 (95% CI 0.81-0.96) and 0.84 (95% CI 0.76-0.93); 2015-2016, 0.94 (95% CI 0.86-1.02) and 0.89 (95% CI 0.80-0.98); 2017-2018, 0.97 (95% CI 0.88-1.07) and 0.94 (95% CI 0.84-1.05); 2019-2020, 0.95 (95% CI 0.84-1.07) and 0.93 (95% CI 0.81-1.06); 2021-2022, 1.00 (95% CI 0.89-1.13) and 0.99 (95% CI 0.86-1.13).
conclusionDespite advancements in RA management over 13 years, fracture incidence may have increased in patients with RA.
