MRI Characteristics Distinguishing Tuberculous Arthritis from Rheumatoid Arthritis: A Comparative Study.
Article in European journal of rheumatology, 2026. 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
objectiveSkeletal tuberculosis (TB) arthritis is an uncommon but significant cause of osteoarticular morbidity, representing less than 1% of all TB cases. Delayed diagnosis often leads to persistent joint stiffness and pain. This study aims to identify early magnetic resonance imaging (MRI) features that distinguish TB arthritis from rheumatoid arthritis (RA).
methodsThe MRI scans were retrospectively analyzed from 2010 to 2017 of 21 patients diagnosed with TB arthritis and 82 patients with RA. Imaging characteristics including synovial effusion, synovial membrane thickness, abscess wall thickness, bony erosions, rice body formation, tenosynovitis, adjacent soft tissue inflammation, and joint space narrowing were compared between the 2 groups.
resultsCompared to RA, TB arthritis patients demonstrated significantly greater abscess wall thickening (P = .001) and rice body formation (P = .008), alongside less pronounced joint space narrowing.
conclusionIn patients presenting with chronic arthritis, the presence of thickened abscess walls, rice bodies, and relatively preserved joint space on MRI serve as early diagnostic markers favoring TB arthritis over RA.
