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

PROTACs are new drug molecules in the beyond Rule of Five (bRo5) chemical space with extremely poor aqueous solubility and intrinsically poor crystallizability due to their structure, which comprises two distinct ligands covalently linked by a flexible linker. This makes PROTACs particularly challenging to understand from a solid-state preformulation perspective. While several X-ray structures have been reported of PROTACs in ternary complexes, to date no structures have been published of single component densely packed PROTACs, from which an understanding of PROTACs' intermolecular interactions, and therefore physical properties, can be developed. An extensive crystallization protocol was applied to grow single crystals of a cereblon-recruiting PROTAC "AZ1" resulting in structures of an anhydrous form and a nonstoichiometric
