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

Drug delivery vectors have the potential to improve the efficacy of therapeutics, including small molecules and nucleic acid-based drugs. However, challenges remain in developing linkages that enable the precise and efficient release of therapeutic cargo in response to mildly acidic environments or lysosomal enzymes. This review highlights recent advances in acid-degradable acetal/ketal and enzyme-cleavable linkages for endolysosomal release. These innovations include the developments of azido-acetal linkers with improved stability and hydrolysis kinetics, organocatalytic trans-isopropenylation for synthesizing asymmetric ketals and their applications in drug delivery, and enzyme-cleavable linkers activated by cathepsin B or β-galactosidase.
