Nuclear import of Cdc13 limits chromosomal capping.
Article in Nucleic acids research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Cdc13 is an essential protein involved in telomere maintenance and chromosome capping. Individual domain analyses on Cdc13 suggest the presence of four distinct OB-fold domains and one recruitment domain. However, it remained unclear how these sub-domains function in the context of the whole protein in vivo. Here, we use individual single domain deletions to address their roles in telomere capping. We find that the OB2 domain contains a nuclear localization signal that is essential for nuclear import of Cdc13 and therefore is required for chromosome capping. The karyopherin Msn5 is important for nuclear localization, and retention of Cdc13 in the nucleus also requires its binding to telomeres. Moreover, Cdc13 homodimerization occurs even if the protein is not bound to DNA and is in the cytoplasm. Hence, Cdc13 abundance in the nucleus and, in consequence, its capping function is strongly affected by nucleo-cytoplasmic transport as well as nuclear retention by DNA binding.
