Yeast Pch2 promotes domainal axis organization, timely recombination progression, and arrest of defective recombinosomes during meiosis.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 110 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
We show that, during budding yeast meiosis, axis ensemble Hop1/Red1 and synaptonemal complex (SC) component Zip1 tend to occur in alternating strongly staining domains. The widely conserved AAA+-ATPase Pch2 mediates this pattern, likely by means of direct intervention along axes. Pch2 also coordinately promotes timely progression of cross-over (CO) and noncross-over (NCO) recombination. Oppositely, in a checkpoint-triggering aberrant situation (zip1Delta), Pch2 mediates robust arrest of stalled recombination complexes, likely via nucleolar localization. We suggest that, during WT meiosis, Pch2 promotes progression of SC-associated CO and NCO recombination complexes at a regulated early-midpachytene transition that is rate-limiting for later events; in contrast, during defective meiosis, Pch2 ensures that aberrant recombination complexes fail to progress so that intermediates can be harmlessly repaired during eventual return to growth. Positive vs. negative roles of Pch2 in the two situations are analogous to positive vs. negative roles of Mec1/ATR, suggesting that Pch2 might mediate Mec1/ATR activity. We further propose that regulatory surveillance of normal and abnormal interchromosomal interactions in mitotic and meiotic cells may involve "structure-dependent interchromosomal interaction" (SDIX) checkpoints.
