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

Transfer RNAs (tRNAs) are central to protein synthesis, ensuring precise decoding of the genetic code by delivering aminoacids to the ribosome. Among all RNA species, tRNAs are the most heavily and diversely modified, with modifications playing critical roles in stability, folding, and function. Here, we present a comprehensive, isodecoder-level map of tRNA modifications in the human pathogen Vibrio cholerae. This map was generated by chemical-based sequencing methods, comparing wild-type and deletion strains. By assigning specific tRNA modifications to their cognate enzymes, we defined a comprehensive modification landscape in Vibrio cholerae and confirmed species-specific features, such as the presence of a functional TrmK enzyme, largely restricted to Gram-positive bacteria. Additionally, we detected a modification at U55 that occurs independently of TruB. To assess the biological significance of these modifications, we evaluated fitness under both standard conditions and subinhibitory antibiotic stress, and examined how modifications in the anticodon stem-loop region influence codon decoding efficiency and accuracy. Based on a comparative analysis of E. coli and V. cholerae, we discuss how species-specific differences in tRNA isodecoder gene repertoires may influence the functional impact and biological importance of tRNA modifications. This work provides the first experimentally validated, genome-wide map of tRNA modifications in V. cholerae, serving as a reference for future research into RNA modifications, translation regulation, and pathogen biology.
