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

It is now established that a small fraction of genomic DNA does adopt the non-canonical B-DNA structure or 'unusual' DNA structure. The unusual DNA structures like DNA-hairpin, cruciform, Z-DNA, triplex and tetraplex are represented as hotspots of chromosomal breaks, homologous recombination and gross chromosomal rearrangements since they are prone to the structural alterations. Friedreich's ataxia (FRDA), the autosomal recessive degenerative disorder of nervous and muscles tissue, is caused by the massive expansion of (GAA) repeats that occur in the first intron of Frataxin gene X25 on chromosome 9q13-q21.1. The purine strand of the DNA in the expanded (GAA) repeat region folds back to form the (R.R*Y) type of triplex, which further inhibits the frataxin gene expression, and this clearly suggests that the shape of DNA is the determining factor in the cellular function. FRDA is the only disease known so far to be associated with DNA triplex. Structural characterization of GAA-containing DNA triplexes using some simple biophysical methods like UV melting, UV absorption, circular dichroic spectroscopy and electrophoretic mobility shift assay are discussed. Further, the clinical aspects and genetic analysis of FRDA patients who carry (GAA) repeat expansions are presented. The potential of some small molecules that do not favour the DNA triplex formation as therapeutics for FRDA are also briefly discussed.
