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

The involvement of genes with expanded tracts of (CAG)n in some neurodegenerative diseases is well established. Whether genes containing these motifs could also have a role in degenerative diseases affecting the retina, which is also neural in origin, is unknown. We investigated (CAG)n expansions as a cause of disease in a panel of eight autosomal dominant retinitis pigmentosa (ADRP) pedigrees, including families known to map to the RP9, RP11, and RP13 loci, using the technique known as "repeat expansion detection" (RED). An expansion was detected in one of the unlinked families, but it did not segregate with the disease and was thus nonpathogenic. Expansions were not detected in any other families. In conclusion, expanded (CAG)n repeats are not the cause of disease in the families we have studied, but given the high level of heterogeneity in RP and in retinal degenerations in general they remain strong candidates for involvement in other forms of retinal dystrophy.
