Y-chromosome lineages and surnames, two blurry trails.
Article in International journal of legal medicine, 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
In societies following the paternal transmission of surnames, their distribution should keep the same trail as that of Y-chromosome lineages. We evaluated this hypothesis by establishing the Y-STR haplotypes of two hundred and thirty-two individuals from the Argentine Northwest, distributed among one hundred and forty-eight surnames. We compared these two sources of information, searching for matches within and through surnames, establishing Median-Joining networks and estimating their time of divergence. We defined two nodal haplotypes (Native American and European), surrounded by the rest. We found cases in which surnames matched Y-STR haplotypes and also recognized identical genetic lineages involving different surnames. These findings suggest that the irregular transmission of surnames in the Argentine Northwest has been higher than that found in other countries. Likewise, similarities between both kinds of lineages should not be taken for granted.
