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

5'-Adenosine monophosphate-activated protein kinase (AMPK) plays a critical role in maintaining cellular energy homeostasis, and its activation has garnered attention for treating chronic metabolic diseases. Inhibitors of AMPK are underdeveloped but bear implications in treating cancers, controlling autophagy, and elderly wasting. Protoberberine alkaloids are typically regarded as AMPK activators. Herein, we report a modular synthesis strategy to access a collection of oxyberberine alkaloids, including the first synthesis of stepharotudine. In vitro assays reveal how subtle structural modifications can negate AMPK activation while conferring unprecedented inhibitory properties within the same class of compounds, which was previously unknown. Key steps in the synthesis include an oxidative Rh(III)-catalyzed C-H functionalization using electron-rich alkenes, NaH-mediated reductive
