Rheumatoid arthritis and the risk of fracture: A Mendelian randomization study.
Article in Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Observational epidemiological studies indicate a higher fracture incidence in rheumatoid arthritis (RA) patients compared to the general population. However, the causal relationship between RA and fracture risk, particularly traumatic and osteoporotic fractures, is not well established. We performed Mendelian randomization (MR) analysis to evaluate the causal relationship between RA and fracture risk. We performed a MR analysis using summary statistics from genome-wide association studies to investigate the causal association between RA and the risk of traumatic fractures at 9 sites and 3 types of osteoporotic fractures. The primary analysis used inverse-variance weighting, supplemented by MR-Egger regression and other methods to assess causal relationships and sensitivity analyses, including heterogeneity and pleiotropy assessments, using R software with appropriate packages. The inverse-variance weighting results demonstrated a causal relationship between genetically predicted RA and an elevated risk of fractures, particularly traumatic fractures of the long bones and osteoporotic fractures, including fractures of shoulder and upper arm (odds ratio [OR] = 1.041, 95% confidence interval [CI]: 1.020-1.062, P = 9.06e-05), fractures of forearm (OR = 1.026, 95% CI: 1.007-1.044, P = .006), fracture of femur (OR = 1.036, 95% CI: 1.009-1.064, P = .009), fractures of lower leg, including joint (OR = 1.031, 95% CI: 1.016-1.047, P = 6.38e-05), fractures of rib(s), sternum, and thoracic vertebrae (OR = 1.041, 95% CI: 1.018-1.064, P = 4.08e-04), osteoporotic with pathological features (OR = 1.128, 95% CI: 1.071-1.188, P = 5.54e-06), postmenopausal osteoporotic with pathological features (OR = 1.060, 95% CI: 1.002-1.123, P = .044), and drug-induced osteoporotic with pathological features (OR = 1.255, 95% CI: 1.124-1.400, P = 5.02e-05). This study highlights the genetic causal link between RA and an increased risk of traumatic and osteoporotic fractures, presenting a new direction for future exploration of the mechanisms underlying RA-related fractures.
