Challenges in case management of brucellosis: a retrospective study from an endemic region.
Article in BMC infectious diseases, 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
backgroundHuman brucellosis remains a significant public health concern in northeastern Türkiye and is among the leading causes of visits to infectious disease clinics. In this study, we aimed to describe the clinical characteristics and laboratory findings of patients with brucellosis in high-burden regions, with a particular focus on identifying diagnostic indicators of complicated disease.
methodsWe conducted a retrospective study of patients with positive serology for brucellosis who were admitted to Harakani State Hospital in Kars between September 2022 and December 2023. Patients were grouped based on whether they had complicated or uncomplicated brucellosis. Potential diagnostic indicators of complicated brucellosis were identified using univariate and multivariate logistic regression.
resultsThe study included 97 patients with a median age of 42 years; 41.2% were female. Rose Bengal and Brucellacapt/Coombs Wright (BC/CW) tests were positive in 94.8% and 98.9% of patients, respectively. Cases were classified as acute (55.7%), subacute (28.9%), and chronic (15.5%). Complicated brucellosis was identified in 33 patients (34%). In univariate analyses, complicated brucellosis was associated with thrombocytopenia (OR: 5.53; 95% CI: 1.01-30.29), elevated C-reactive protein (CRP) (OR: 5.9; 95% CI: 2.31-15.15), elevated erythrocyte sedimentation rate (ESR) (OR: 3.23; 95% CI: 1.14-9.18), and a BC/CW titer >1:320 (OR: 2.76; 95% CI: 1.13-6.72). Elevated CRP levels were observed in 43.3% of patients and remained independently associated with complicated brucellosis in multivariable analysis (adjusted OR: 4.36; 95% CI: 1.60-11.87). Relapse occurred in 13 patients (13.4%) within six months.
conclusionsThe presence of thrombocytopenia, high CRP and ESR levels, and high BC/CW titers was a diagnostic indicator of complicated brucellosis. Early identification of high-risk patients using combined clinical and laboratory parameters may improve follow-up strategies and clinical outcomes.
