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

Class I histone deacetylases regulate gene transcription and are established therapeutic targets. HDAC1-3 form the catalytic subunit in several distinct multiprotein complexes; however, HDAC inhibitors are rarely studied in the context of these complexes. We evaluated multiple inhibitors, using seven HDAC complexes, and found that the inhibition profiles were highly complex-dependent, despite targeting the same enzyme. We also investigated the effect of the allosteric regulator inositol phosphate on these inhibitors. We observed very large, complex-selective reductions in the potency of benzamides bearing a "foot-pocket group", proposed to be selective for HDAC1/2. The potencies of these compounds are likely to be profoundly different
