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

Ligands bind to an occluded orthosteric ligand-binding pocket within the nuclear receptor ligand-binding domain. Molecular simulations have revealed theoretical ligand entry/exit pathways to the orthosteric pocket; however, it remains unclear whether ligand binding proceeds through induced fit or conformational selection mechanisms. Here, using nuclear magnetic resonance spectroscopy, isothermal titration calorimetry, and surface plasmon resonance analysis, we provide evidence that structurally distinct agonists bind peroxisome proliferator-activated receptor γ (PPARγ) via a two-step induced fit mechanism involving an initial fast kinetic step followed by a slow conformational change. The agonist encounter complex binding pose is suggested in crystal structures where ligands bind to a surface pore suggested as a ligand entry site in molecular simulations. Our findings suggest an activation mechanism for PPARγ whereby agonist binding occurs through an initial encounter complex followed by a transition of the ligand into the final binding pose within the orthosteric pocket, inducing a transcriptionally active conformation.
