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
The study of two variable amplicons of rye indicates that RYS1, a mobile element, is activated during tissue culture. We propose that RYS1 could be a foldback (FB) transposon. The FB transposons have been rarely reported in plants; RYS1 is the first described in rye and also the first active plant FB transposon reported. Preferential integration points in the rye genome exist, because the new insertions seem to be located, in all studied cases, in the same genome positions. We assume that RYS1 became active in rye very recently, as different plants from in vivo-growing cultivars showed that these elements were present or absent in the same genomic position in which the in vitro-activated element was found. This high rate of modification in these particular loci, both in the in vivo and in vitro populations, could indicate that probably the mechanisms promoting genetic variability in nature are the same that induce variation in vitro, and the modifications induced by somaclonal variation could be already present in vivo populations.
