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 concept of 'super agonism' has been described since the discovery of peptide hormone analogues that yielded greater functional responses than the endogenous agonists, in the early 1980s. It has remained an area of debate as to whether such compounds can really display greater efficacy than an endogenous agonist. However, recent pharmacological data, combined with crystal structures of different GPCR conformations and improved analytical methods for quantifying drug action, are starting to shed light on this phenomenon and indicate that super agonists may be more than superstition.
