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

βAsp is an isomer of Asp that can be formed by either deamidation of Asn or isomerization of Asp and known as biological clock. The presence of βAsp affects the proteolytic stability of the protein. Formation of the isomerized Asp plays a diverse and crucial role in aging, cancer, autoimmune, neurodegenerative, and other diseases. A number of methods have been developed to detect βAsp, and they are usually used in conjunction. Because of identical mass, differentiation of βAsp and Asp residues is challenged. Degradation of βAsp is still unclear and needed to be explored. The energetics and mechanism of five possible pathways for cleavages at βAsp in peptide model have been investigated by DFT/B3LYP/6-311 +  + G(d,p) level of the theory. The calculations show that peptide bond cleavage at α-chain (amino side) due to αO
