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

Demodex mites inhabit the pilosebaceous unit despite harsh environmental conditions including UV radiation, variable salinity, and cosmetics. Their recently characterized endobacterium may contribute to this resilience. This study aimed to elucidate mechanisms of the microbe-host interaction that help mites withstand environmental stress. The genome of Corynebacterium kroppenstedtii subsp. demodicis was sequenced using PacBio technology and annotated via MicroScope. Metabolic and symbiotic traits were analyzed using KEGG and compared with the Demodex folliculorum secretome from published transcriptome data. The complete 2,456,075 bp genome contains 2034 coding sequences and exhibits reduced variable genes compared to other Corynebacterium species. Primary metabolism comprises an almost complete minimal gene set but lacks two tRNA synthetases and genes for phosphatidylethanolamine and NAD
