Evaluation of propidium monoazide for 16S ribosomal RNA metabarcoding assessment of microbial communities in 60-day ripened raw goat milk cheese.

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
Cheese ripening is a complex microbial process marked by significant shifts in microbial composition. Considering that propidium monoazide (PMA) depletes DNA from nonviable cells, we hypothesized that PMA treatment of cheese samples could affect the microbiota characterization of 60-d-ripened raw goat curd cheese by 16S rRNA metabarcoding sequencing. After ripening, PMA-treated and nontreated (control) samples from the same cheese units were processed for DNA extraction, library preparation, and 16S rRNA metabarcoding sequencing on an Illumina MiSeq platform. Downstream bioinformatic analyses for microbial diversity assessment were performed using QIIME 2 and the phyloseq package in R. Statistical analyses included permutational multivariate analysis of variance (PERMANOVA), Wilcoxon tests, and linear discriminant analysis effect size (LEfSe). No significant differences were observed in either α or β diversity metrics between PMA-treated and nontreated samples. However, PMA treatment significantly reduced the abundance of farm environment-associated
