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

motivationAmplicon sequencing of 16S rRNA and internal transcribed spacer (ITS) gene regions is the most widely used approach for characterizing bacterial and fungal communities. The DADA2 pipeline has become the standard for inferring amplicon sequence variants (ASVs), offering single-nucleotide resolution over traditional OTU clustering. However, executing the full DADA2 workflow requires R programming proficiency and manual coordination of multiple sequential steps, presenting a substantial barrier for researchers in clinical, environmental, and agricultural sciences who lack computational training.

resultsWe present RAPID (R-based Amplicon Pipeline for Interactive DADA2), a pair of R/Shiny applications providing complete graphical user interfaces for 16S rRNA and ITS amplicon analysis. The 16S application implements a 10-step guided workflow from raw paired-end FASTQ files through quality filtering, denoising, paired-read merging, chimera removal, SILVA-based taxonomy assignment, phyloseq construction with data transformation (rarefaction, relative abundance, or CLR), visualization (rarefaction curves, alpha diversity, NMDS, PCoA, abundance), PERMANOVA, and ANCOM-BC2 differential abundance analysis. The ITS application extends this to 11 steps, adding automated primer removal via cutadapt with support for multiple primers and length-variable amplicons, and uses the UNITE database for fungal taxonomy. Both applications feature asynchronous background processing, session persistence, real-time progress monitoring, publication-ready figure export at 300 DPI, and comprehensive CSV/PNG result downloads. AVAILABILITY: Raw 16S rRNA amplicon sequences are available in the NCBI Sequence Read Archive under BioProject accession PRJNA1499817. RAPID is freely available at https://github.com/beantkapoor786/RAPID and archived at 10.5281/zenodo.21628564. Both applications can be installed locally on any system with R (≥4.0) and run as local web applications.
