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

Despite the critical conservation status of many harlequin toads (Anura: Bufonidae: Atelopus) and their significance in elucidating the impacts of emerging diseases on amphibians, genomic data for this genus are scarce. Here, we present a de novo genome assembly of the Santa Marta Harlequin Toad, Atelopus laetissimus, using PacBio HiFi sequencing data, representing the first published Atelopus genome assembly and only the second amphibian genome assembly from Colombia. The assembly consists of 1,487 contigs at 35× coverage with an N50 of 31 Mb and a total length of 3.5 Gb. A Tetrapoda BUSCO score of 92% suggests our assembly is very nearly complete. Analysis revealed a high repeat content, with 70% of the genome consisting of interspersed repeats. This high-contiguity draft assembly will drive the search for a possible genetic basis of pathogen resistance in these endangered toads of the Sierra Nevada de Santa Marta, as well as facilitate ongoing evolutionary studies.
