Gene duplication and deletion caused by over-replication at a fork barrier.
Article in Nature communications, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Replication fork stalling can provoke fork reversal to form a four-way DNA junction. This remodelling of the replication fork can facilitate repair, aid bypass of DNA lesions, and enable replication restart, but may also pose a risk of over-replication during fork convergence. We show that replication fork stalling at a site-specific barrier in fission yeast can induce gene duplication-deletion rearrangements that are independent of replication restart-associated template switching and Rad51-dependent multi-invasion. Instead, they resemble targeted gene replacements (TGRs), requiring the DNA annealing activity of Rad52, the 3'-flap nuclease Rad16-Swi10, and mismatch repair protein Msh2. We propose that excess DNA, generated during the merging of a canonical fork with a reversed fork, can be liberated by a nuclease and integrated at an ectopic site via a TGR-like mechanism. This highlights how over-replication at replication termination sites can threaten genome stability in eukaryotes.
