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

Identification of protein carbonylation because of covalent attachment of a lipid peroxidation end-product was performed by combining proteolytic digestion followed by solid-phase hydrazide enrichment and liquid chromatography (LC)-electrospray ionization (ESI) tandem mass spectrometry (MS/MS) using both collision-induced dissociation (CID) and electron capture dissociation (ECD). To evaluate this approach, we selected apomyoglobin and 4-hydroxy-2-nonenal (4-HNE) as a model protein and a representative end-product of lipid peroxidation, respectively. Although the characteristic elimination of 4-HNE (156 Da) in CID was found to serve as a signature tag for the modified peptides, generation of nearly complete fragment ion series because of efficient peptide backbone cleavage (in most cases over 75%) and the capability to retain the labile 4-HNE moiety of the tryptic peptides significantly aided the elucidation of primary structural information and assignment of exact carbonylation sites in the protein, when ECD was employed. We have concluded that solid-phase enrichment with both CID- and ECD-MS/MS are advantageous during an in-depth interrogation and unequivocal localization of 4-HNE-induced carbonylation of apomyoglobin that occurs via Michael addition to its histidine residues.
