Tibetan Y-STR trait in the eleven regions of the Qinghai-Tibet Plateau.
Article in International journal of legal medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Y-Chromosomal short-tandem repeats (Y-STRs) could provide highly valuable information for forensic investigation and demographic studies. However, there is still no systematic Y-STR information on Tibetan as obtained from different regions of the broad Qinghai-Tibet Plateau. In this study, an analysis was conducted on 585 male individuals, classed into 3 different dialect branches as Ü-Tsang, Amdo, and Khams and originating from 11 scattered regions of the Qinghai-Tibet Plateau. The gene diversity values of the 41 Y-STRs in Tibetan ranged from 0.3636 to 0.9322. Additionally, a total of 563 distinct haplotypes were obtained with an overall haplotype diversity of 0.9999 and a discrimination capacity of 0.9624. As suggested by the inter-population diversity analysis, there were two main separated clades of Tibetan subgroups. The visualization of pairwise genetic distances between 11 Tibetan subgroups and 59 reference populations using cladogram revealed the distribution of various populations, which was basically consistent with the patterns of geographic origin and linguistic affinity.
