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 tandem repeats of trinucleotide sequences are present in many human genes and their expansion in specific genes causes a number of hereditary neurological disorders. The normal function of triplet repeats in transcripts is barely known and the role of expanded RNA repeats in the pathogenesis of Triplet Repeat Expansion Diseases needs to be more fully elucidated. Here we have described the structures formed by transcripts composed of AAG, CAG, CCG, CGG and CUG repeats, which were determined by chemical and enzymatic structure probing. With the exception of the repeated AAG motif, all studied repeats form hairpin structures and these hairpins show several alternative alignments. We have determined the molecular architectures of these co-existing hairpin structures by using transcripts with GC-clamps which imposed single alignments of hairpins. We have provided experimental evidence that CCUG repeats implicated in myotonic dystrophy type 2 also form hairpin structures with properties similar to that composed of the CUG repeats.
