Methyl CpG binding protein 2 (MeCP2) enhances photodimer formation at methyl-CpG sites but suppresses dimer deamination.
Article in Nucleic acids research, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Spontaneous deamination of cytosine to uracil in DNA is a ubiquitous source of C→T mutations, but occurs with a half life of ∼50 000 years. In contrast, cytosine within sunlight induced cyclobutane dipyrimidine dimers (CPD's), deaminate within hours to days. Methylation of C increases the frequency of CPD formation at PyCG sites which correlate with C→T mutation hotspots in skin cancers. MeCP2 binds to mCG sites and acts as a transcriptional regulator and chromatin modifier affecting thousands of genes, but its effect on CPD formation and deamination is unknown. We report that the methyl CpG binding domain of MeCP2 (MBD) greatly enhances C=mC CPD formation at a TCmCG site in duplex DNA and binds with equal or better affinity to the CPD-containing duplex compared with the undamaged duplex. In comparison, MBD does not enhance T=mC CPD formation at a TTmCG site, but instead increases CPD formation at the adjacent TT site. MBD was also found to completely suppress deamination of the T=mCG CPD, suggesting that MeCP2 may have the capability to both suppress UV mutagenesis at PymCpG sites as well as enhance it.
