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

This article describes a simple method for accurate rapid amplification of complementary deoxyribonucleic acid (cDNA) ends (RACE), the distinctive feature being that only a gene-specific primer is used, without an anchor or adapter primer. Under these conditions, Thermus aquaticus (Taq) polymerase synthesizes cDNA ends exactly, so that amplified products obtain a characteristic structure: a terminal inverted repeat composed of a gene-specific primer and occasionally several nucleotides from its 3' flanking sequence. These structures suggest a hypothetical mechanism of cDNA end synthesis in which Taq DNA polymerase synthesizes a sequence complementary to the gene-specific primer at the 3' end of the daughter strand by switching the template to the 5' terminal region through circularization of the DNA. As a result, the targeted cDNA will be efficiently amplified with only a single gene-specific primer. This technique, which provides highly specific amplification of the 5' and 3' ends of a cDNA, is especially useful for isolation of cDNA when the corresponding messenger ribonucleic acid is scarce.
