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

Three new isatin-pyridine-2-oxime hybrids (AM01-03) were synthesized and experimentally evaluated as reactivators of acetylcholinesterase (AChE) inhibited by a surrogate of the nerve agent A-242, in comparison with their 4-oxime isomers previously reported by our research group. Furthermore, the interactions of these molecules within the AChE/A-242 complex were assessed through docking and molecular dynamics (MD) simulations. Our results show that the 2-oxime isomers, unlike their 4-oxime analogues, can reactivate AChE inhibited by the A-242 surrogate at 100 µM and are even capable of outperforming the commercial reactivator HI-6. These findings suggest that isatin-oxime hybrids may exhibit a specific biological activity-similar to that observed for obidoxime and trimedoxime-in the reactivation of AChE inhibited by A-242.
