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

Pasteurella canis is a Gram-negative bacterium commonly found as a commensal organism in the oral cavity of dogs and cats. Human infections are rare and typically occur following skin breaches, with bacteremia reported less frequently. To date, fatal central nervous system infections in adults caused by P. canis have not been reported. We report the case of a 25-year-old immunocompetent man with no significant medical history. The patient developed otitis a few days after his dog licked his ear. Twenty days later, he died at home following a febrile illness with headaches. An autopsy revealed purulent meningitis. Bacteriological cultures from the ear and subdural empyema isolated P. canis and Streptococcus anginosus group. To our knowledge, this is the first reported case of fatal adult meningoencephalitis caused by P. canis. The case highlights the pathogen's invasive potential and underscores the importance of prompt evaluation of otitis with neurological involvement.
