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

backgroundSingle Nucleotide Polymorphisms (SNPs) have emerged as valuable markers in human identification when short tandem repeat analysis fails to solve casework.

methodsThe panel of 94 identity-informative SNPs included in the ForenSeq™ DNA Signature Prep Kit was evaluated in Mexican Mestizo populations using massively parallel sequencing. A total of 104 samples from three geographic regions were analyzed and combined with 357 previously published profiles from Nuevo León, Jalisco, and Mexico City to generate a national dataset (n = 461). Forensic parameters, genetic differentiation, and population structure were assessed across regions.

resultsHigh combined power of discrimination, minimal population substructure, and low interpopulation differentiation were observed. The low differentiation between populations supports the use of a unified national SNP database for human identification purposes.

conclusionsThe results support the use of a unified national iiSNP reference database for forensic human identification in Mexico. To our knowledge, this is the most comprehensive iiSNP reference dataset for the Mexican population to date, integrating regional data to establish a national framework for forensic applications.
