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
Repetitive sequences are ubiquitous and fast-evolving elements responsible for size variation and large-scale organization of plant genomes. Within tribe Phaseoleae (Fabaceae), some genera, such as Phaseolus, Vigna, and Cajanus, show small genome and mostly stable chromosome number. Here, we applied a combined computational and cytological approach to study the organization and diversification of repetitive elements in some species of these genera. Sequences were classified in terms of type and repetitiveness and the most abundant were mapped to chromosomes. We identified long terminal repeat (LTR) retrotransposons, especially Ogre and Chromovirus elements, making up most of genomes, other than P. acutifolius and Vigna species. Satellite DNAs (SatDNAs) were less representative, but highly diverse among species, showing a clear phylogenetic relationship. In situ localization revealed preferential location at pericentromeres and centromeres for both types of sequences, suggesting a heterogeneous composition, especially for centromeres. Few elements showed subterminal accumulation. Copy number variation among chromosomes within and among species was observed for all nine identified SatDNAs. Altogether, our data pointed two main elements (Ty3/Gypsy retrotransponsons and SatDNAs) to the diversification on the repetitive landscape in Phaseoleae, with a typical set of repeats in each species. The high turnover of these sequences, however, did not affect total genome size.
