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

This study investigates the genetic structure and demographic history of contemporary Thai populations from Tak and Ranong, two border provinces between Thailand and Myanmar with complex immigration histories. We analyzed 20 Y-SNP markers (327 samples) and 24 Y-STR profiles (241 samples), along with published datasets, and observed significant genetic differentiation between these regions. Tak is dominated by O2a2b1a1a (44.53%) and O1b1a1a (21.17%). The presence of NO1 (14.6%) suggests genetic contributions from nearby populations such as the Karen, Lawa, and Khuen. Notably, Tak shows low gene diversity (GD) at the DYS391 (0.2208), contrasting with Ranong (0.5247) and the overall Thailand population (0.4708). Ranong exhibits a more diverse haplogroup distribution, with prominent frequencies of O1b1a1a (20.75%), F (16.98%) and O2a2b1a1a (13.21%). The presence of haplogroups K (11.32%) and R* (7.55%) reflects a genetic connection with the Maniq or other mainland Negrito groups, as well as historical gene flow from South Asia. These findings enhance our understanding of the genetic landscape shaped by migration and localized admixture. We also expanded the Thailand Y-chromosome database with novel Y-STR haplotypes, updated forensic parameters and Y-haplogroup frequencies, providing valuable resources for paternal ancestry inference and kinship verification in both forensic science and population genetics.
