piRAT: piRNA Annotation Tool for annotating, analyzing, and visualizing piRNAs.
Article in BMC bioinformatics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIn recent years, Piwi-interacting RNAs (piRNAs) have been found to be involved in different biological roles beyond their initially identified role in protecting the germline genome. However, there is a lack of robust computational tools that facilitate their accurate annotation, analysis, and visualization, which would allow large-scale analysis of piRNAs across samples and species.
resultsWe present piRAT, a piRNA Annotation Tool for annotating both primary piRNAs from piRNA clusters and secondary piRNAs generated via the ping-pong cycle, using small RNA-seq data mapped to a genome. piRAT also performs descriptive analyses and generates comprehensive reports with visualizations to support annotations and provide further insights.
conclusionsIn our comparative analyses, piRAT emerged as the most comprehensive tool available in terms of functionalities. It consistently produced higher-quality annotations of piRNA clusters and ping-pong sites and generated the most detailed reports. As piRAT requires no prior annotations or special data preprocessing, it is a versatile choice for any species, particularly for non-model organisms.
