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

A combination of experimental and theoretical approaches is used to decipher the molecular recognition event of benzoic acid complexed with protein kinase A. The publicly known crystal structure suggests the protonated form of benzoic acid to be complexed with Protein Kinase A. Such a protonation pattern of is unlikely for benzoic acid in aqueous environment and must be induced by complexation to protein kinase A. Unfortunately, isothermal titration calorimetry does not reveal any binding event, which may be due to low affinity. However, Poisson-Boltzmann calculations and molecular dynamics simulations strengthen the initial hypothesis of a protonated benzoic acid binding to protein kinase A.
