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

The olm (Proteus anguinus), with a predicted maximum lifespan of more than 100 years, is the longest-lived amphibian, which in addition possesses a range of unique adaptations to its dark, subterranean cave habitat. To assess the underlying molecular signatures, we present the first comprehensive transcriptome of the olm. Our study provides gene expression data across six organs and comparative genomics analyses, accessible via an interactive web server: http://comp-pheno.de/olm . The data uncover significant organ-specific gene expression, with the brain showing the highest number of organ-specific expressed genes. Our findings reveal significantly more genes under strong negative selection than positive selection, particularly in brain-specific expressed genes. Processes under positive selection in the olm resemble those in other long-lived species.
