1 · What the graph read from it

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.

2 · The registry

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

Genome integrity is essential for cellular survival and adaptation across diverse physiological states. The fission yeast Schizosaccharomyces pombe relies on conserved DNA repair pathways to maintain genome stability during proliferative growth and in the absence of cell division (quiescence/G0). Using 5-fluoroorotic acid (5-FOA) counter-selection, we examined spontaneous mutation accumulation in both conditions in a wild-type prototrophic strain. Unexpectedly, we identified in growing and quiescent cells a class of 5-FOA-resistant mutants that, unlike canonical ura4 or ura5 loss-of-function mutants, retain the ability to grow without uracil supplementation. Genetic analyses showed that this phenotype is stable and segregates as a single locus. Whole-genome sequencing of tetrads from independent crosses revealed multiple hypomorphic alleles of ura6, which encodes the essential uridylate kinase. These alleles, comprising non-synonymous substitutions and an in-frame duplication, cluster within conserved regions of the protein and likely reduce production of the toxic 5-FOA-derived metabolite while preserving sufficient uracil biosynthesis.
