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

Bacterial adenosine diphosphate-ribosyltransferases (ADPRTs) are toxins that play a significant role in pathogenicity by inactivating host proteins through covalent addition of ADP-ribose. In this study we used ADP-ribosylated Kemptide (LRRASLG) as a standard to examine the effectiveness of three common tandem mass spectrometry fragmentation methods for assignment of amino acid sequence and site of modification. Fragmentation mechanisms investigated include low-energy collision-induced dissociation (CID), infrared multiphoton dissociation (IRMPD), and electron-capture dissociation (ECD); all were performed on a hybrid linear ion trap Fourier transform ion cyclotron resonance mass spectrometer. We show that ECD, but neither CID nor IRMPD, of ADP-ribosylated Kemptide produces tandem mass spectra that are interpretable with regard to amino acid sequence assignment and site of modification. Examination of CID and IRMPD tandem mass spectra of ADP-ribosylated Kemptide revealed that fragmentation was primarily focused to the ADP-ribose region, generating several potential diagnostic ions for use in discovery of ADP-ribosylated proteins. Because of the lower relative sensitivity of ECD during data-dependent acquisition to CID, we suggest a 2-fold strategy where CID and IRMPD are first used to detect ADP-ribosylated peptides, followed by sequence assignment and location of modification by ECD analysis.
