Evaluating the diagnostic utility of the slide agglutination method for brucellosis in Saudi Arabia: A retrospective study at International Medical Center, Jeddah, Saudi Arabia.

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
backgroundBrucellosis, a prevalent zoonotic disease in endemic regions like Saudi Arabia, poses diagnostic challenges due to its nonspecific clinical manifestations. This disease is endemic in various regions, including the Mediterranean basin, the Middle East, Asia, Africa, and Latin America. This retrospective study is designed to evaluate the diagnostic utility of the slide agglutination method for brucellosis. By examining its sensitivity, specificity, and overall performance, this research will provide insights into the reliability of the slide agglutination method as a diagnostic tool in a high-prevalence setting.
methodsThis retrospective study, conducted at the International Medical Center, Jeddah, compared the real-world diagnostic performance of the Slide Agglutination Method (SAM) with gold-standard blood cultures and Brucella serology. Over 734 cases (37 Brucella-positive and 697 Brucella-negative) were reviewed between 2019 and 2022.
resultsSAM achieved 86.5% sensitivity and 99.3% specificity, with an average turnaround time of 2.32 hours. In contrast, blood culture showed 40.9% sensitivity and 94.5% accuracy, and conventional serology demonstrated comparable sensitivity but longer processing times.
conclusionSAM combines speed, simplicity, and robust accuracy, making it an ideal first-line screen for acute brucellosis in endemic, resource-limited settings. However, its performance in chronic or low-titer infections remains less well characterized. Our detailed operational metrics fill a local evidence gap and support the Saudi Ministry of Health in updating national screening guidelines.
