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

A method based on the multiplex polymerase chain reaction (PCR) and gel electrophoresis for the comparative analysis of gene expression levels was developed. Using the method many cDNA fragments from different sources can be compared simultaneously. Competitive PCR amplification of expressed genes from different sources was performed by using 'module-shuffling primers' (MPSs). The MPSs (labeled with different fluorophores) consist of sequence modules of 3 or 4 nt. The modules are arranged in different orders in each primer; therefore, the base sequences of the primers are different but their melting temperatures are identical. The genes expressed in different sources are ligated with tags complementary with the MPSs. Tag-ligated fragments are mixed in one tube and amplified at the same amplification efficiency by the MPSs. Amplified fragments are detected separately by multiple-color gel electrophoresis. This method can detect different amounts of each expressed gene, up to a difference in amounts of 30%, and its detection limit is 0.1 amol per assay.
