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

Nanopore DNA sequencing is limited by low base-calling accuracy. Improved base-calling accuracy has so far relied on specialized base-calling algorithms, different nanopores and motor enzymes, or biochemical methods to re-read DNA molecules. Two primary error modes hamper sequencing accuracy: enzyme mis-steps and sequences with indistinguishable signals. We vary the driving voltage from 100 to 200 mV, with a frequency of 200 Hz, across a Mycobacterium smegmatis porin A (MspA) nanopore, thus changing how the DNA strand moves through the nanopore. A DNA helicase moves the DNA through the nanopore in discrete steps, and the variable voltage moves the DNA continuously between these steps. The electronic signal produced with variable voltage is used to overcome the primary error modes in base calling. We found that single-passage de novo base-calling accuracy of 62.7 ± 0.5% with a constant driving voltage improves to 79.3 ± 0.3% with a variable driving voltage. The variable-voltage sequencing mode is complementary to other methods to boost the accuracy of nanopore sequencing and could be incorporated into any enzyme-actuated nanopore sequencing device.
