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 stepwise partially overlapping primer-based PCR (SWPOP-PCR) method for isolating flanking unknown DNA regions was developed, which comprises three rounds of nested PCRs sequentially driven by SWPOP primer-nested specific primer pairs. SWPOP primer set is characterized by a partial overlap of 10 bp with 3'-part of the latter primer is identical to 5'-part of the former one, which makes the SWPOP primer in use anneal to SWPOP site of the prior PCR product only at relatively low temperature. For each PCR, target single-stranded DNA primed by the SWPOP primer in the exclusive one low-stringency cycle is converted into double-stranded form in the following high-stringency cycle due to the presence of a perfect annealing site for the specific primer. This double-stranded DNA bounded by the specific primer and the SWPOP primer is exponentially amplified in the remaining high-stringency cycles. Non-target single-stranded DNA, however, cannot be amplified given the lack of perfect complementary sequences for any primers. Therefore, the partial overlap of a SWPOP primer set preferentially synthesizes target products but inhibits nonspecific amplification. We successfully exploited SWPOP-PCR to obtain the DNA sequences flanking glutamate decarboxylase gene (gadA) locus in Lactobacillus brevis NCL912 and hygromycin gene (hyg) integrated in rice.
