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

Lacticaseibacillus paracasei bacteremia associated with probiotic use is rare. We report a 71-year-old man with advanced lung cancer who developed L. paracasei bacteremia while ingesting a commercially available probiotic-fermented milk. Autopsy demonstrated direct tumor invasion and perforation of the mid-esophagus, providing a structural route for bacterial translocation from the gastrointestinal lumen into the bloodstream. Genetic analysis showed that the blood isolate was genetically identical to the probiotic strain contained in the ingested product. Bacteremia resolved with antibiotics, but the patient died of respiratory failure from progression of the malignancy. This case highlights that probiotic organisms, despite an established safety profile, can cause bacteremia when immunocompromise coexists with disruption of the gastrointestinal barrier.
