An annotated dataset of Gram stains from positive blood cultures.
Article in Scientific data, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Bloodstream infections (BSIs) of high morbidity and mortality are across all age groups, and urgent for accurate intervention. Gram stain interpretation of positive blood cultures (PBCs) is crucial for early diagnosing BSIs, yet this manual process is labor-intensive, time-consuming, and highly operator-dependent. Artificial intelligence (AI)-assisted microscopic interpretation of stained smears presents beneficial to microbiology diagnostics. Addressing the auto-identification of blood-culture Gram stains, this study introduces a dataset of Gram-stain smears collected in clinical practice. The dataset includes 505 microscopic images, covering up to 57 species associated with BSIs, with a total of 7528 annotations. These annotations categorized by staining characteristics and morphological features into cocci, bacilli, and fungi. We trained and validated an object detection model based on the YOLOv10 architecture on this dataset to automatically localize and classify these morphological categories in microscopic images. The publicly released dataset will help developments that utilize artificial intelligence to auto-interpretate the Gram stains from PBCs for routine clinical application.
