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

Researchers face a significant problem in PCR amplification of DNA fragments with high GC contents. Analysis of these regions is of importance since many regulatory regions of different genes and their first exons are GC-rich. There are a large number of protocols for amplification of GC-rich DNA, some of which perform well but are costly. Most of the economical protocols fail to perform consistently, especially on products with >80 % GC contents and a size of >300 bp. One of these protocols requires multiple additions of DNA polymerase during thermal cycling which therefore rules out its utility if a large number of samples have to be amplified. We have established a method for simultaneous amplification of specific PCR products from a large number of human DNA samples using general laboratory reagents. These amplicons have GC contents ranging from 65-85 % and sizes up to 870 bp. The protocol uses a PCR buffer containing co-solvents including 2-mercaptoethanol and bovine serum albumin for amplification of DNA. A specific thermal cycling profile is also used which incorporates a high annealing temperature in the first 7 cycles of the reactions. The PCR products are suitable for different molecular biology applications including sequencing.
