Limiting homologous recombination at stalled replication forks is essential for cell viability: DNA2 to the rescue.
Review in Current genetics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
The disease-associated nuclease-helicase DNA2 has been implicated in DNA end-resection during DNA double-strand break repair, Okazaki fragment processing, and the recovery of stalled DNA replication forks (RFs). Its role in Okazaki fragment processing has been proposed to explain why DNA2 is indispensable for cell survival across organisms. Unexpectedly, we found that DNA2 has an essential role in suppressing homologous recombination (HR)-dependent replication restart at stalled RFs. In the absence of DNA2-mediated RF recovery, excessive HR-restart of stalled RFs results in toxic levels of abortive recombination intermediates that lead to DNA damage-checkpoint activation and terminal cell-cycle arrest. While HR proteins protect and restart stalled RFs to promote faithful genome replication, these findings show how HR-dependent replication restart is actively constrained by DNA2 to ensure cell survival. These new insights disambiguate the effects of DNA2 dysfunction on cell survival, and provide a framework to rationalize the association of DNA2 with cancer and the primordial dwarfism disorder Seckel syndrome based on its role in RF recovery.
