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 gas-phase linearization of cyclotides via site-selective ring opening at dehydroalanine residues and its application to cyclotide sequencing is presented. This strategy relies on the ability to incorporate dehydroalanine into macrocyclic peptide ions, which is easily accomplished through an ion/ion reaction. Triply protonated cyclotide cations are transformed into radical cations via ion/ion reaction with the sulfate radical anion. Subsequent activation of the cyclotide radical cation generates dehydroalanine at a single cysteine residue, which is easily identified by the odd-electron loss of ·SCH
