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.
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
Endoplasmic reticulum (ER) phagy is the form of selective autophagy that governs ER abundance and integrity by targeting dysfunctional ER fragments for degradation. How the recognition of ER fragments as autophagy substrates is coupled to engagement of the core autophagic machinery is largely unknown. Here, using a combination of in vitro reconstitution systems, structural modeling, and cell biology, we demonstrate that ER membrane receptors directly engage the core autophagy component ATG9A, as well as the PI3P-binding protein WIPI2, to initiate ER-associated autophagosome biogenesis. ER-phagy receptor-ATG9A association nucleates the recruitment of the other key autophagy proteins required to initiate ER-phagy. In parallel, ER-phagy receptor-WIPI2 engagement promotes rapid LC3 lipidation for autophagic membrane expansion. These data show how ER-phagy receptors trigger the cascade of events leading to ER autophagosome formation.
