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

The epigenetic remodeling of chromatin histone proteins by acetylation has been the subject of recent investigations searching for biomarkers indicative of late onset cognitive loss. Histone acetylations affect the regulation of gene transcription, and the loss of learning induced deacetylation at specific histone sites may represent biomarkers for memory loss and Alzheimer's disease (AD). Selected-reaction-monitoring (SRM) has recently been advanced to quantitate peptides and proteins in complex biological systems. In this paper, we provide evidence that SRM-based targeted proteomics can reliably quantify specific histone acetylations in both AD and control brain by identifying the patterns of H3 K18/K23 acetylations Results of targeted proteomics assays have been validated by Western blot (WB) analysis. As compared with LC-MS/MS-TMT (tandem-mass-tagging) and WB methods, the targeted proteomics method has shown higher throughput, and therefore promised to be more suitable for clinical applications. With this methodology, we find that histone acetylation is significantly lower in AD temporal lobe than found in aged controls. Targeted proteomics warrants increased application for studying epigenetics of neurodegenerative diseases.
