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

Cytosine methylation is an epigenetic modification that regulates transcription. DNA demethylation occurs through oxidation of methylcytosine to hydroxymethylcytosine, making hydroxymethylation an important and translationally relevant marker of DNA methylation dynamics. These epigenetic modifications can be measured in their deoxynucleoside forms from enzymatically digested DNA by liquid chromatography-mass spectrometry (LC-MS). However, 5-hydroxymethyl-2'-deoxycytidine (5hmdC) co-elutes with 2'-deoxycytidine (dC). Because 5hmdC represents <0.05% of total dC in DNA, co-elution with dC causes ion suppression that limits detection and quantitation. Here, we present a chromatographic method that separates 5hmdC from dC, eliminates ion suppression, and improves the sensitivity of 5hmdC detection.
