Genetic variation of 15 autosomal STR loci in the southern region population of KSA: A forensic DNA analysis study.
Article in Journal of Taibah University Medical Sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Short tandem repeats (STRs) are highly polymorphic genetic markers with essential roles in forensic identification and paternity testing. Understanding the genetic diversity of STR loci in specific populations is crucial for accurate forensic applications. The aims of this study were to evaluate the genetic variation and forensic efficiency parameters for 15 autosomal STR loci in the southern region population of KSA. Methods: Buccal swabs were collected from 150 unrelated native Saudi individuals from the southern region. DNA extraction was performed using Chelex 100, followed by quantification using a Quantifiler® Duo DNA Kit. STR amplification was conducted using an AmpFlSTR® Identifiler® Plus Kit, and capillary electrophoresis was performed with a Genetic Analyzer 3130. Statistical analyses were conducted using GeneAlex 6.5 and Powerstats v12 software. Results: In total, 140 different alleles were observed across the 15 STR loci, with 6.57073827 × 10 Conclusion: The high informativity observed for the 15 STR loci in the southern Saudi population demonstrates their usefulness for forensic and paternity testing applications.
