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

The ability of cells to power energy-demanding processes depends on maintaining the ATP hydrolysis reaction a billion-fold away from equilibrium. Cells respond to alterations in the energy state by sensing changes in the ratio of ATP, ADP, AMP, and inorganic phosphate levels. A key barrier to understanding how this happens is a lack of tools for direct manipulation of the energy state in living cells. Here, we introduce ATPGobble-a genetically encoded tool that hydrolyzes ATP in vivo. ATPGobble increases the metabolic rate, decreases [ATP]/[ADP] and [ATP]/[AMP] ratios, and activates AMPK in human cells. We performed a systematic analysis of proteome and phosphoproteome changes caused by ATPGobble, and found that it remodels cytoskeleton, cell cycle, and translation machinery. Our results establish ATPGobble as a powerful new tool for dissecting the regulatory roles of energy state in living cells.
