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
The Drosophila TTK protein is involved in the processes of cell differentiation and is represented by two isoforms, TTK69 and TTK88, which have a common N-terminal BTB domain and different C-terminal sequences. Earlier, it was shown that TTK69 represses the activity of enhancers and promoters by recruiting a conserved among higher eukaryotes NURD complex to chromatin. The Mep-1 protein was found in the NURD-complex of Drosophila, and this protein can interact with the C-terminal region of TTK69. In the present study, using the yeast two-hybrid system, we mapped the interacting regions of the TTK and Mep-1 proteins. We identified regions in the unique C-terminal regions of TTK isoforms that can interact simultaneously with two regions of the Mep-1 protein. The results show that, despite the low homology of the C-terminal regions, the TTK isoform retains the ability to interact with two conserved regions of the Mep-1 protein, which suggests the functional significance of this interaction.
