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

MeltMADGE reconfigures the mutation scanning process of denaturing gradient gel electrophoresis so that the independent variable is time rather than space and the dependent (denaturing) variable is temperature rather than concentration of chemical denaturant. Use of a thermal ramp enables the use of a homogeneous gel and therefore of high-density arrays of wells such as those of microplate array diagonal gel electrophoresis (MADGE). In this configuration, electrophoresis of products on 10-12 96-well meltMADGE gels can be conducted in a 1- to 2-liter tank in a 1- to 2-h run, enabling the scanning of a target amplicon in over 1,000 subjects simultaneously. Gels are read by imaging the fluorescence of UV-excited ethidium bromide, giving a simple, economical system for identifying rarer sequence variants in target genes; it is suitable for large-scale case-control or population studies and other comparable applications. Different amplicons with similar melting characteristics can also be combined in the same run.
