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

In this paper we describe a novel method for detecting many DNA fragments through efficient amplification by using an emulsion system based on "on-chip" PCR instead of conventional multiplex polymerase chain reaction (PCR). During the preparation of on-chip PCR, a set of primers were immobilized on a slide and other sets were in an emulsion system. Different emulsion phase primers and other related PCR components were dispersed in different droplets of the emulsion system, and then, due to the thermal instability of emulsion droplets, they would be released onto the surface of the slide after preheating in the first PCR step. To test the above method, we used plasma DNAs from pregnant women who was carrying a male fetus for gender identification. Four different Y chromosome DNA fragments were selected. Results showed that different DNA fragments could be simultaneously amplified with satisfactory results. It is suggested that a simple, convenient and inexpensive on-chip PCR method has been developed.
