Age-related length variability of polymorphic CAG repeats.
Article in DNA repair, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Somatic instability of CAG repeats has been associated with the clinical progression of CAG repeat diseases. Aging and DNA repair processes influence the somatic stability of CAG repeat in disease and in mouse models. However, most of the studies have focused on genetically engineered transgenic repeats and little is known about the stability of naturally polymorphic CAG repeats. To study whether age and/or DNA repair activity have an effect on the somatic stability of CAG repeats, we analyzed variations of the length of naturally polymorphic CAG repeats in the striatum of young and aged WT and ogg1 KO mice. Some multiple and long polymorphic CAG repeats were observed to have variable length in the striatum of aged mice. Interestingly, a low level of repeat variability was detected in the CAG repeat located in tbp, the only mouse polymorphic CAG repeat that is associated with a trinucleotide disease in humans, in the striatum of aged mice and not in young mice. We propose that age may have an effect on the somatic stability of polymorphic CAG repeats and that such an effect depends on intrinsic CAG repeat characteristics.
