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
Kar3, a Saccharomyces cerevisiae Kinesin-14, is essential for karyogamy and meiosis I but also has specific functions during vegetative growth. For its various roles, Kar3 forms a heterodimer with either Cik1 or Vik1, both of which are noncatalytic polypeptides. Here, we present the first biochemical characterization of Kar3Cik1, the kinesin motor that is essential for karyogamy. Kar3Cik1 depolymerizes microtubules from the plus end and promotes robust minus-end-directed microtubule gliding. Immunolocalization studies show that Kar3Cik1 binds preferentially to one end of the microtubule, whereas the Kar3 motor domain, in the absence of Cik1, exhibits significantly higher microtubule lattice binding. Kar3Cik1-promoted microtubule depolymerization requires ATP turnover, and the kinetics fit a single exponential function. The disassembly mechanism is not microtubule catastrophe like that induced by the MCAK Kinesin-13s. Soluble tubulin does not activate the ATPase activity of Kar3Cik1, and there is no evidence of Kar3Cik1(.)tubulin complex formation as observed for MCAK. These results reveal a novel mechanism to regulate microtubule depolymerization. We propose that Cik1 targets Kar3 to the microtubule plus end. Kar3Cik1 then uses its minus-end-directed force to depolymerize microtubules from the plus end, with each tubulin-subunit release event tightly coupled to one ATP turnover.
