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

β-Lactam-resistant bacterial infections are a serious concern worldwide. A common mechanism of β-lactam resistance is the expression of β-lactamases, which are capable of hydrolyzing the β-lactam bond in the most commonly used β-lactam antibiotics. Metallo-β-lactamases (MBLs) utilize 1 or 2 zinc ions for catalysis. One of the three most clinically relevant MBLs is Imipenemase (IMP). An important potential way to combat MBLs is to use an inhibitor in combination with an existing β-lactam drug. The current study investigates the mechanism of inhibition of preclinical boronic acid β-lactamase inhibitor RPX 7546 and mercaptomethyl bisthiazolidine D-CS319, which are two previously reported MBL inhibitors, with IMP-1 and its variant IMP-78 (V67F/S262G), chosen due to its improved efficiency hydrolyzing carbapenem β-lactams. A combination of analytical and biochemical experiments and
