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

To elucidate the origin and migration history of the "Mansen elements," a group of temperate grassland plants mainly distributed in northeastern Asia, phylogeographic analyses based on chloroplast DNA markers and double-digest restriction site-associated DNA sequencing (ddRAD-seq) data were performed on Viola orientalis, one of the representative species of the group. Phylogenetic analyses using ddRAD-seq data revealed that the populations of V. orientalis were clustered into five clades, among which the continental clades made of populations from Russia and Korea diverged more than 100,000 years earlier than the Japanese clades. The Japanese clade likely diverged during the last glacial period, followed by a further post-glacial divergence into the Kyushu and the Honshu subclades. Our study demonstrated that V. orientalis originated in the continental area of northeastern Asia and, during the last glacial period, has spread southward through the Korean Peninsula across the Japanese Islands. This finding supports the previously proposed evolutionary hypothesis regarding the origin and migration routes of the Mansen elements.
