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

Self-cleavable linkers offer controlled payload release without the need for external stimuli, making them valuable for applications in chemical biology and clinical settings. In this work, we expand the scope of the β-eliminative cleavable linkers developed by Santi and coworkers to include the release of carboxylic acids. We demonstrate that the half-life of the ensuing ester conjugates can be controlled by varying electron-withdrawal using a pendant aryl sulfone moiety. The nascent ester group hydrolyzes readily in mouse serum but is stable in human serum. This system offers a tunable, autonomous release mechanism that could enable the delivery of new payloads in therapeutic contexts.
