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
Atg8 is a central protein in bulk starvation-induced autophagy, but it is also specifically associated with multiple protein targets under various physiological conditions to regulate their selective turnover by the autophagy machinery. Here, we describe two new closely related Arabidopsis thaliana Atg8-interacting proteins (ATI1 and ATI2) that are unique to plants. We show that under favorable growth conditions, ATI1 and ATI2 are partially associated with the endoplasmic reticulum (ER) membrane network, whereas upon exposure to carbon starvation, they become mainly associated with newly identified spherical compartments that dynamically move along the ER network. These compartments are morphologically distinct from previously reported spindle-shaped ER bodies and, in contrast to them, do not contain ER-lumenal markers possessing a C-terminal HDEL sequence. Organelle and autophagosome-specific markers show that the bodies containing ATI1 are distinct from Golgi, mitochondria, peroxisomes, and classical autophagosomes. The final destination of the ATI1 bodies is the central vacuole, indicating that they may operate in selective turnover of specific proteins. ATI1 and ATI2 gene expression is elevated during late seed maturation and desiccation. We further demonstrate that ATI1 overexpression or suppression of both ATI1 and ATI2, respectively, stimulate or inhibit seed germination in the presence of the germination-inhibiting hormone abscisic acid.
