Nunataks or massif de refuge? A phylogeographic study of Rhodiola crenulata (Crassulaceae) on the world's highest sky islands.
Article in BMC evolutionary biology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
backgroundQuaternary climatic oscillations had tremendous effects on the current distribution of species. Here, we aim to elucidate the glacial history of Rhodiola crenulata, a perennial herb almost exclusively restricted to rock crevices on mountain peaks, and to test whether the nunatak or massif de refuge hypotheses could explain its distribution pattern.
resultsSix haplotypes and six ribotypes were detected in the cpDNA data set and the ITS data set, respectively. The divergence of R. crenulata and its closest relatives was dated have occurred ca. 0.65 Mya, during the Naynayxungla glaciation on the QTP. Mismatch distribution analysis suggested that the species experienced a range expansion around 0.31 Mya. Populations with high genetic and haplotype diversity were found on the QTP platform as well in the Hengduan Mountains. The ecological niche modeling results showed that there were suitable habitats on both the QTP platform and in the Hengduan Mountains during the LGM.
conclusionOur results support a scenario that both nunataks and the massif de refuge hypotheses could explain the distribution of R. crenulata. We also confirmed that Quaternary climatic oscillations could promote plant speciation in some circumstances. This study adds to a growing body of evidence suggesting that the QTP plant lineages exhibited diverse reactions to the Quaternary climatic oscillations.
