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

Food digestion is essential for nutrient absorption, supporting protein synthesis and maintaining endoplasmic reticulum (ER) homeostasis. However, whether animals can sense ER stress and suppress digestion to reduce ER overload remains unclear. Here, we show that Caenorhabditis elegans can sense ER stress and shut down digestion as a protective response. Food intake activates the unfolded protein response in the ER, and loss of its central regulator, XBP-1, impairs digestion, highlighting the importance of ER homeostasis in food digestion. We identify FDR-1, a food-induced protein, as a key factor that promotes digestion by preserving ER balance through its interaction with DPY-11. Disruption of FDR-1 triggers the innate immune p38/PMK-1 pathway, leading to a protective shutdown of digestion to mitigate ER stress. These findings reveal an adaptive mechanism by which animals limit digestion under ER stress and suggest that modulating nutrient intake may offer therapeutic strategies for diseases related to ER dysfunction.
