1 · What the graph read from it

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.

2 · The registry

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

backgroundGranulomatous omentitis is a relatively rare but significant inflammatory condition in sheep, often associated with persistent bacterial infections. Dual infection with Trueperella pyogenes and Corynebacterium pseudotuberculosis is rare, and detailed studies elucidating their combined role in disease pathogenesis remain limited.

objectivesThis study investigated the occurrence, pathological features, and microbial aetiology of granulomatous omentitis in sheep from a slaughterhouse in Rey, Iran, with a focus on molecular detection of T. pyogenes and C. pseudotuberculosis.

methodsA total of 6000 sheep were inspected post-mortem between 2022 and 2024. Gross examination identified omental nodules, from which tissue samples were collected. Histopathological analysis, PCR amplification of species-specific genes, and correlation of molecular findings with histology were performed.

resultsNodular omental lesions were present in 0.5% of examined sheep. Histopathology demonstrated granulomatous inflammation characterized by epithelioid macrophages, multinucleated giant cells, and central caseous necrosis. PCR confirmed co-infection in all cases (25/25). The pathological and molecular evidence suggests a synergistic role of both pathogens in chronic omental inflammation.

conclusionsThese findings highlight the importance of considering co-infections in granulomatous omentitis and suggest that future studies should focus on the pathogenesis of dual infections and the development of effective control measures, such as targeted vaccination strategies.
