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

Spatiotemporal regulation of key-node signaling molecules, such as 3',5'-cyclic adenosine monophosphate (cAMP)-dependent protein kinase (PKA), is critical for normal cell physiology and susceptible to dysregulation in disease. Liquid-liquid phase separation (LLPS) is broadly recognized as a fundamental component of signal regulation, yet the connections between physiological and disease-linked biomolecular condensates are not well understood. Here, we show that an understudied, brain-specific PKA regulatory subunit, RIβ, forms biomolecular condensates with distinct features from the ubiquitous isoform, RIα. We demonstrate that two RIβ mutants linked to neurodegenerative (L50R) or neurodevelopmental (R335W) pathologies produce aberrant condensates that trap the PKA catalytic subunit within a gel-like matrix or cAMP-insensitive holoenzyme complex, respectively. RIβ
