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

backgroundThe incidence of Candida tropicalis isolation is increasing in hospital settings. High azole resistance and mortality rates make it a pathogen that requires further analysis.

methodsFourteen azole resistant Candida glabrata clinical isolates were collected from a Lebanese hospital and analysed through whole genome sequencing for single nucleotide polymorphisms in key resistance and virulence genes, and for phylogenetic relatedness. Isolates were then characterised for pathogenicity related attributes.

resultsAll isolates had Lys314Glu mutation in ERG20 with multiple isolates displaying numerous shared mutations, such as Glu291Lys in CDR2 and Ala16Thr in CDR3. With the exception of two isolates that clustered together, most isolates were over 99.6% identical based on a genomic heatmap, implying high relatedness consistent with localised clonal expansion, although SNP differences appeared too high to support this. However, the isolates exhibited increased ergosterol and chitin content, as well as upregulation of drug efflux pumps resulting in drug resistance.

conclusionOur hospital isolates showed convergent resistant pathways, with many isolates having both shared and unique mutations and a high degree of genomic similarities.
