Enhanced pathogen identification in fungal endophthalmitis by metagenomic next-generation sequencing: a retrospective clinical evaluation.

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
Fungal endophthalmitis (FE) is a vision-threatening emergency that requires rapid pathogen identification. Conventional microbial culture demonstrates limited sensitivity in FE, warranting improved diagnostic approaches. We evaluated the detection performance of unbiased metagenomic next-generation sequencing (mNGS) in 31 clinically diagnosed FE cases, including 16 vitreous humor (VH) and 15 aqueous humor (AH) specimens. mNGS showed a positivity rate of 90.3% (28/31, 95% CI: 74.2%-98%), outperforming culture (9.1%, 2/22, 95% CI: 1.1%-29.2%). The positivity rates were 100% for endogenous FE and 85% for exogenous FE, while VH and AH specimens achieved 100% and 80% positivity, respectively. mNGS identified polymicrobial infections in 5 exogenous cases, and a total of 15 fungal species across 9 genera, dominated by Aspergillus flavus, Candida albicans, and Aspergillus niger. Candida albicans and Aspergillus flavus were the predominant pathogens in endogenous and exogenous FE, respectively. Notably, mNGS enabled detection of rare fungal species including Aspergillus niger, Aspergillus welwitschiae, Fusarium oxysporum, Memnoniella echinata, Rhizopus oryzae, Rhizopus microsporus, Chaetomium globosum, and Debaryomyces fabryi. Sequencing results were supported or supplemented by culture, beta-D-glucan, and galactomannan testing in selected cases. Among mNGS-positive cases, 82.1% (23/28) experienced clinical management changes guided by fungal identification. We further propose a laboratory workflow integrating mNGS with conventional assays, tailored to the obtained specimen volume of intraocular fluids.
