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

Macrophages exposed to immune stimuli reprogram their epigenomes to alter their subsequent functions. Exposure to bacterial lipopolysaccharide (LPS) causes widespread nucleosome remodeling and the formation of thousands of de novo enhancers. We dissected the regulatory logic by which the network of interferon regulatory factors (IRFs) induces the opening of chromatin and the formation of de novo enhancers. We found that LPS-activated IRF3 mediated de novo enhancer formation indirectly by activating the type I interferon (IFN)-induced ISGF3. However, ISGF3 was generally needed to collaborate with IRF1, particularly where chromatin was less accessible. At these locations, IRF1 was required for the initial opening of chromatin, with ISGF3 extending accessibility and promoting the deposition of H3K4me1, marking poised enhancers. Because
