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 convergent syntheses of homogeneous disulfide cross-linked polypeptides are reported. Reducible polypeptides were synthesized containing four and eight dodecapeptides in two and three linear conjugation steps. Critical for the convergent methodology was the use of orthogonally protected cysteines as either acetamidomethyl (Acm) or Fmoc-thiazolidine (Thz). Both groups could be selectively deprotected with silver trifluoromethanesulfonate in the presence of internal disulfide bonds using TFA and aqueous conditions, respectively. This approach allows for large, reducible polypeptides to be synthesized in efficient yields and minimizes the number of conjugation steps, allowing the development and optimization of gene delivery polypeptides containing multiple peptide components necessary to overcome the numerous
