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

backgroundOttowia massiliensis sp.nov. is a slow-growing and Gram-stain-negative bacillus, first isolated from the stool sample of a healthy volunteer. Due to its slow growth and challenging cultivation, it is easily overlooked in clinical microbiology laboratories. This case report is the first case of its pathogenicity. CASE PRESENTATION: This case report describes a case of canaliculitis caused by Ottowia massiliensis sp.nov. The patient, an 80-year-old woman, presented with bilateral epiphora and discharge lasting for 4 years, which worsened with redness and swelling over the past week. Microbial culture of the lacrimal duct secretion after 72 h on Columbia blood agar showed small colonies. MALDI-TOF MS did not yield accurate results, but 16 S rDNA sequencing identified the bacterium as Ottowia massiliensis sp.nov. (LT960589.1). Antimicrobial sensitivity tests showed high activity against most ophthalmic drugs.

conclusionsIn the case described here, we discuss the diagnosis and treatment strategies for eye infections caused by Ottowia massiliensis sp.nov., laying the foundation for improving clinical and laboratory awareness of this bacterium.
