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

This Letter describes the further lead optimization of the VU0486321 series of mGlu1 positive allosteric modulators (PAMs), focused on addressing the recurrent issue of plasma instability of the phthalimide moiety. Here, we evaluated a number of phthalimide bioisosteres, and ultimately identified isoindolinones as the ideal replacement that effectively address plasma instability, while maintaining acceptable mGlu1 PAM potency, DMPK profile, CNS penetration and mGluR selectivity.
