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

Various hair follicle (HF)-associated disorders, such as acne vulgaris, hidradenitis suppurativa, and alopecia areata, are linked to dysbiosis, an imbalance between resident and pathogenic microbes. Characterization of the HF and skin microbiome employs techniques such as 16S rRNA gene sequencing and metagenomic shotgun sequencing, with the latter providing comprehensive taxonomic and functional insights. However, relic DNA from dead microbes and free environmental DNA can persist in samples, meaning that metagenomic data does not exclusively reflect living microbiota. For functional studies on HF dysbiosis or to assess potential therapeutic interventions, we describe here how propidium monoazide (PMA) treatment can be performed before (metagenomics) sequencing to distinguish viable microbial communities. Furthermore, we exemplify qPCR and (fluorescent) in situ hybridization (ISH) of two alternative viability screening methods for the HF and scalp microbiome.
