Genome of the extinct Gotland cattle breed.
Article in BMC genomics, 2025. 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
backgroundThe extinct cattle breed Gotland cattle lived on the island of Gotland in the Baltic Sea until the beginning of the 1950s. We sequenced the genomes of two Gotland cattle isolated from skulls from a local museum on Gotland.
resultsThe depth of coverage was 2.7X and 3.3X, respectively, with a breadth of coverage of 85% and 89%. Based on coverage of the sex chromosomes, both animals appeared to be female. We detected 19 million single nucleotide variants and 2.8 million indels in the joint dataset of Gotland cattle jointly called with modern Swedish cattle. In a principal component analysis, the two Gotland cattle placed the closest to Swedish Red cattle, rather than among the southern or northern traditional breeds. In terms of mitochondrial haplotypes, they were similar to clusters of related haplotypes involving multiple other breeds, including Swedish Mountain cattle, Swedish Red Polled and several Finnish cattle breeds.
conclusionsIn summary, our results suggest that Gotland cattle were genetically closer to the ancestors of Swedish Red cattle than to the extant traditional Swedish breeds.
