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

Bisulfite sequencing is a valuable tool for mapping the position of 5-methylcytosine in the genome at single base resolution. However, the associated chemical treatment causes strand scission, which depletes the number of sequenceable DNA fragments in a library and thus necessitates PCR amplification. The AT-rich nature of the library generated from bisulfite treatment adversely affects this amplification, resulting in the introduction of major biases that can confound methylation analysis. Here, we report a method that enables more accurate methylation analysis, by rebuilding bisulfite-damaged components of a DNA library. This recovery after bisulfite treatment (ReBuilT) approach enables PCR-free bisulfite sequencing from low nanogram quantities of genomic DNA. We apply the ReBuilT method for the first whole methylome analysis of the highly AT-rich genome of Plasmodium berghei. Side-by-side comparison to a commercial protocol involving amplification demonstrates a substantial improvement in uniformity of coverage and reduction of sequence context bias. Our method will be widely applicable for quantitative methylation analysis, even for technically challenging genomes, and where limited sample DNA is available.
