Article in Arquivos de gastroenterologia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundNon-alcoholic steatohepatitis (NASH) is becoming a leading cause of liver disease in the US, while Rheumatoid arthritis (RA) affects a significant portion of the global population. In recent times, newer drugs have been developed to slow down the progression of RA, one of which is hydroxychloroquine (HCQ). Despite HCQ being linked to slowly progressive transaminitis, its role in the development of NASH remains unclear. Our research fills this gap by examining the prevalence and risk factors of developing NASH in patients with RA on HCQ.
methodsThis retrospective cohort study analyzed 619,350 adult patients diagnosed with RA. Data were sourced from a multicenter database covering over 360 hospitals across 26 healthcare systems in the US from 1999 to September 2022, excluding pregnant individuals. Multivariate regression analysis assessed the risk of NASH, adjusting for confounders including smoking history, male gender, dyslipidemia, hypertension, type 2 diabetes mellitus, obesity, and hydroxychloroquine use. Statistical significance was set at P<0.05, with analyses conducted using R version 4.0.2 (R Foundation for Statistical Computing, Vienna, Austria, 2008).
resultsIn a cohort of 79.4 million individuals, 619,350 non-pregnant subjects had rheumatoid arthritis, with 3,080 diagnosed with NASH, while 616,270 did not. Patients with NASH displayed a higher prevalence of smoking history, hyperlipidemia, hypertension, type 2 diabetes mellitus, obesity, and HCQ use. Multivariate regression analysis identified increased NASH risk in smokers (OR: 1.24; 95%CI: 1.14-1.36), males (OR: 0.88; 95%CI: 0.81-0.96), individuals with dyslipidemia (OR: 1.34; 95%CI: 1.21-1.47), hypertension (OR: 1.11; 95%CI: 1.00-1.27), type 2 diabetes mellitus (OR: 3.24; 95%CI: 2.98-3.54), obesity (OR: 3.59; 95%CI: 3.31-3.89), and hydroxychloroquine use (OR: 1.79; 95%CI: 1.65-1.94).
conclusionRA patients on HCQ showed an increased prevalence and odds of developing NASH, even after adjusting for common confounding factors. This indicates that HCQ may play a role in the development of hepatic steatosis and fibrosis. Clinicians should consider this association to prevent advanced liver disease. Future research should focus on optimal screening for early detection and enhancing patient outcomes.
background• The study investigates the relationship between nonalcoholic steatohepatitis (NASH) and rheumatoid arthritis (RA), analyzing the impact of hydroxychloroquine (HCQ) use on the development of NASH.
background• HCQ slows the progression of RA; however, its effect on the liver is not yet fully understood.
