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

Mechanism-based inhibitors of class A beta-lactamases, such as sulbactam, undergo a complex series of chemical reactions in the enzyme active site. Formation of a trans-enamine acyl-enzyme via a hydrolysis-prone imine is responsible for transient inhibition of the enzyme. Although the imine to enamine tautomerization is crucial to inhibition of the enzyme, there are no experimental data to suggest how this chemical transformation is catalyzed in the active site. In this report, we show that E166 acts as a general base to promote the imine to enamine tautomerization.
