1 · What the graph read from it

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.

2 · The registry

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

C to T mutation hotspots in skin cancers occur primarily at methylated CpG sites that coincide with sites of UV-induced cyclobutane pyrimidine dimer (CPD) formation. These mutations are proposed to arise from the insertion of A by DNA polymerase η opposite the T that results from deamination of the methylC ((m)C) within the CPD. Although the frequency of CPD formation and repair is modestly modulated by its rotational position within a nucleosome, the effect of position on the rate of (m)C deamination in a CPD has not been previously studied. We now report that deamination of a T(m)C CPD whose sugar phosphate backbone is positioned against the histone core surface decreases by a factor of 4.7, whereas that of a T(m)C CPD positioned away from the surface increases by a factor of 8.9 when compared with unbound DNA. Because the (m)Cs undergoing deamination are in similar steric environments, the difference in rate appears to be a consequence of a difference in the flexibility and compression of the two sites due to DNA bending. Considering that formation of the CPD positioned away from the surface is also enhanced by a factor of two, a T(m)CG site in this position might be expected to have up to an 84-fold higher probability of resulting in a UV-induced (m)C to T mutation than one positioned against the surface. These results indicate that rotational position may play an important role in the formation of UV-induced C to T mutation hotspots, as well as in the mutagenic mechanism of other DNA lesions.
