Titration of repeat-induced point mutation (RIP) by chromosome segment duplications in Neurospora crassa.
Article in Genetica, 2008. 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
Repeat-induced point mutation (RIP) is a hypermutational process that alters duplicated DNA sequences in Neurospora crassa. In previous studies, five of six large ( > 100 kb) chromosome segment duplications (Dp's) examined were shown to dominantly suppress RIP in smaller (< 5 kb) duplications. The suppressor duplications were > 270 kb, whereas the lone non-suppressor duplication was approximately 117 kb. We have now screened another 33 duplications and found 29 more suppressors and four more non-suppressors. All 22 suppressor duplications whose size could be estimated were > 270 kb, whereas two newly identified non-suppressor duplications examined were 140-154 kb. RIP was suppressed in a subset of crosses heterozygous for more than one ordinarily non-suppressor duplication. These results strengthen the hypothesis that large duplications titrate out the RIP machinery and suggest the "equivalence point" for the titration is close to 300 kb.
