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

Lafora disease is a rare and fatal progressive myoclonus epilepsy characterized by the accumulation of insoluble glycogen deposits in the brain and peripheral tissues. Mutations in the gene encoding the glycogen phosphatase laforin result in Lafora disease. Currently, there are no laforin-specific chemical probes, limiting our understanding of the roles of laforin in glycogen metabolism and other cellular processes. Here, we identified sulfophenyl acetic amide (SPAA), as a novel nonhydrolyzable phosphotyrosine mimetic for laforin inhibition. Using fragment-based and scaffold-hopping strategies, we discovered several highly potent and selective active site-directed laforin inhibitors. Among them, compound
