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

Chromatin immunoprecipitation (ChIP) serves as a central experimental technique in epigenetics research, yet there are serious drawbacks: it is a relative measurement, which untethered to any external scale obscures fair comparison among experiments; it employs antibody reagents that have differing affinities and specificities for target epitopes that vary in abundance; and it is frequently not reproducible. To address these problems, we developed Internal Standard Calibrated ChIP (ICeChIP), wherein a native chromatin sample is spiked with nucleosomes reconstituted from recombinant and semisynthetic histones on barcoded DNA prior to immunoprecipitation. ICeChIP measures local histone modification densities on a biologically meaningful scale, enabling unbiased trans-experimental comparisons, and reveals unique insight into the nature of bivalent domains. This technology provides in situ assessment of the immunoprecipitation step, accommodating for many experimental pitfalls as well as providing a critical examination of untested assumptions inherent to conventional ChIP.
