Robust imputation-based method for eye, hair, and skin colour prediction from low-coverage ancient DNA.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The prediction of externally visible traits (eye, hair, and skin colours) from DNA can provide valuable information for contemporary and ancient human populations. The validated HIrisPlex-S method is the primary tool in forensics for phenotyping modern samples. The HIrisPlex-S multiplex PCR assay can handle trace DNA from modern samples, but the analysis of degraded, low-coverage ancient DNA (aDNA) presents additional challenges. Genotype imputation has recently proven successful in effectively filling in missing information in aDNA sequences. To assess the feasibility of this approach, we evaluated how key factors, such as genome coverage, minor allele frequency, extent of postmortem damage, and the population origin of the test individual, influence the efficiency of imputing HIrisPlex-S markers and predicting phenotypes. We used high-coverage sequence data from modern individuals and ancient remains for the evaluation. Our results demonstrate that even with genome coverages as low as 0.1–0.5×, the proposed workflow can predict phenotypes from degraded ancient (or forensic) whole genome sequence (WGS) data with good accuracy. To aid the archaeogenetics community, we have developed aHISPlex. This user-friendly, easily deployable imputation-based framework includes the new bioinformatics tools and the pre-made reference data sets required for the whole analysis.
