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

We developed a Southern blotting based method that uses rare cutting restriction endonucleases and electrophoresis of single stranded DNA to detect junction fragments resulting from the rearranged dystrophin gene. By conventional Southern blot hybridisation, no junction fragments were detected in 27 unrelated patients with Duchenne (DMD) or Becker (BMD) muscular dystrophy, who had 20 deletions and seven duplications in the dystrophin gene. With our new method, junction fragments were detected in 21 of these 27 patients. When the junction fragments were used as markers, five carriers were unequivocally diagnosed among six females from two families of DMD/ BMD patients. This novel method allows simple and definitive identification of carriers with risk factors for DMD/BMD without using quantitative Southern blot hybridisation.
