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
In Schizosaccharomyces pombe, heterochromatin spread, which is marked by histone 3 lysine 9 methylation (H3K9me), requires the chromodomains (CDs) of the H3K9 methylase Suv39/Clr4 and the HP1/Swi6 protein. It is unclear how the actions of these two H3K9me-recognizing CDs are coordinated. We find that the intrinsic preference of Suv39/Clr4 is to generate dimethylated H3K9 product. The recognition of pre-existing H3K9me marks by the CD of Suv39/Clr4 stimulates overall catalysis, enabling the accumulation of small amounts of trimethylated product in vivo. Coincidentally, the Suv39/Clr4 CD, unlike the HP1/Swi6 CD, has been shown to prefer the trimethyl state over the dimethyl state. We show that this preference enables efficient heterochromatin spread in vivo by reducing competition with HP1 proteins for the more prevalent dimethyl state. Our results reveal a strategy by which "writers" and "readers" of a chromatin mark exploit different methylation states on the same residue in order to facilitate collaboration and avoid competition.
