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

introductionChromobacterium violaceum is a facultative, Gram-negative, motile bacillus that rarely causes human infections, but could lead to severe disease with high mortality when systemic spread occurs. Reported infections include bacteremia, septicemia, wound infections, skin lesions, respiratory tract infections, and rarely urinary tract infections. CASE PRESENTATION: We report a rare case of C. violaceum isolated from the urine of a 35-year-old female from the Dagomba ethnic group in the Northern Region of Ghana who presented with a recurrent right flank pain and right upper quadrant abdominal pain at the Tamale Teaching Hospital. The organism was identified through biochemical testing and whole genome sequencing. The infection resolved after two doses of azithromycin (500 mg) and five doses of metronidazole (400 mg).

conclusionHuman infection with Chromobacterium violaceum is extremely rare in Ghana. This case represents the first documented C. violaceum-associated urinary tract infection in the country and provides detailed perspectives into its biochemistry, antimicrobial susceptibility, and genomic characteristics. Greater clinical and laboratory awareness of this pathogen is essential for timely diagnosis and management of similar rare infections.
