Limitations of serial cloning in mammals.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Mammals can now be cloned artificially, but it remains unknown whether they can also maintain their species through cloning. Herein, we continued serial cloning for 20 years from a single donor mouse. These re-cloned mice appeared normal and had normal lifespans, but large structural and lethal mutations accumulated in their DNA with each generation. The birth rate of serial cloning began to decline from the 27th generation, and the 58th generation was the last. When re-cloned mice from near the final generation were mated with males, their oocytes could be fertilized, but most embryos degenerated. However, a few embryos were normalized by meiosis and fertilization and developed to full term, suggesting that mammals rely on sexual rather than asexual reproduction to eliminate genetic anomalies caused by clonal reproduction.
