Novel Phagocytosis-Resistant Extended-Spectrum β-Lactamase-Producing Escherichia coli From Keratitis.
Article in JAMA ophthalmology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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
importanceExtended-spectrum β-lactamase (ESBL)-producing Escherichia coli are highly antibiotic resistant, and primary ocular infection by ESBL E coli has rarely been reported. A novel mutation conferring phagocytosis resistance would position a strain well to infect the cornea. OBSERVATIONS: A woman with recurrent keratitis presented with a corneal ulcer, which was culture positive for ESBL E coli. Resistant to nearly all other antimicrobials, the infection was treated with amikacin and polymyxin B-trimethoprim, and the ulcer resolved over 3 weeks. Analysis of the E coli genome showed it to belong to multilocus sequence type 131 (ST131). This isolate was found to possess a novel deletion in yrfF, an essential regulator of bacterial capsule synthesis. Disruption of yrfF, which confers mucoidy and increased virulence, has not been previously observed in ESBL E coli from any infection site. This novel variant was experimentally proven to cause the mucoid phenotype, and corresponding resistance to phagocytic killing. CONCLUSIONS AND RELEVANCE: Increased resistance to immune clearance in an ESBL E coli lineage already known for its virulence is an unsettling development. This phenotype, which likely positioned it as an unusual cause of corneal ulcer, can be easily recognized in the laboratory, which should help limit its spread.
