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 the original manuscript, we reported the demonstration of an integrated microfluidic chip that performed helicase dependent amplification (HDA) on samples containing live bacteria. Bacterial lysis, nucleic acid extraction, and DNA amplification with a fluorescent reporter were incorporated into a disposable polymer cartridge format. We reported that the device was able to detect as few as 10 colony-forming units (CFU) of E. coli in growth medium. While the main conclusions of the original paper remain sound, the data presented in support of those conclusions contained errors that we detail, discuss and correct here. In short, we misidentified a non-specific product as a specific product of our HDA reaction. We incorrectly called reactions containing the non-specific product (length 70 bp) positive. Further investigation demonstrated that our primer set was faulty and not capable of amplifying the specific product. Here we redesigned primers, sequenced all of the products and reran all of the experiments reported previously to generate a new, verified dataset.
