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
Sex chromosome differentiation is subject to independent evolutionary processes among different lineages. The accumulation of repetitive DNAs and consequent crossing-over restriction guide the origin of the heteromorphic sex chromosome region. Several Neotropical fish species have emerged as interesting models for understanding evolution and genome diversity, although knowledge of their genomes is scarce. Here, we investigate the content of repetitive DNAs between males and females of Apareiodon sp. based on large-scale genomic data focusing on W sex chromosome differentiation. In Apareiodon, females are the heterogametic sex (ZW) and males are the homogametic sex (ZZ). The genome size estimate for Apareiodon was 1.2 Gb (with ~ 42× and ~ 47× coverage for males and females, respectively). In Apareiodon sp., approximately 36% of the genome was composed of repetitive DNAs and transposable elements (TEs) were the most abundant class. Read coverage analysis revealed different amounts of repetitive DNAs in males and females. The female-enriched clusters were located on the W sex chromosome and were mostly composed of microsatellite expansions and DNA transposons. Landscape analysis of TE contents demonstrated two major waves of invasions of TEs in the Apareiodon genome. Estimation of TE insertion times correlated with in situ locations permitted the inference that helitron, Tc1-mariner, and CMC EnSpm DNA transposons accumulated repeated copies during W chromosome differentiation between 20 and 12 million years ago. DNA transposons and microsatellite expansions appeared to be major players in W chromosome differentiation and to guide modifications in the genome content of the heteromorphic sex chromosomes.
