A factor in a wild isolated Neurospora crassa strain enables a chromosome segment duplication to suppress repeat-induced point mutation.

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
Repeat-induced point mutation (RIP) is a sexual stage-specific mutational process of Neurospora crassa and other fungi that alters duplicated DNA sequences. Previous studies from our laboratory showed that chromosome segment duplications (Dps) longer than (approx.) 300 kbp can dominantly suppress RIP, presumably by titration of the RIP machinery, and that although Dps less than 200 kbp did not individually suppress RIP, they could do so in homozygous and multiply heterozygous crosses, provided the sum of the duplicated DNA exceeds (approx.) 300 kbp. Here we demonstrate suppression of RIP in a subset of progeny carrying the normally sub-threshold 154 kbp Dp(R2394) from a cross of T(R2394) to the wild isolated Carrefour Mme. Gras strain (CMG). Thus, the CMG strain contains a factor that together with Dp(R2394) produces a synthetic RIP suppressor phenotype. It is possible that the factor is a cryptic Dp that together with Dp(R2394) can exceed the size threshold for titration of the RIP machinery and thereby causes RIP suppression.
