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
Mitophagy is essential for mitochondrial quality control, selectively removing damaged or superfluous mitochondria to maintain cellular health and metabolic homeostasis. While positive regulators of mitophagy are relatively well characterized, the mechanisms governing its downregulation remain less understood. In this study, we investigate the role of Saccharomyces cerevisiae Slm35 - a protein previously involved in oxidative stress response - in the regulation of mitophagy. We discovered that Slm35 is a soluble mitochondrial matrix protein and functions as a novel negative regulator of mitophagy and the mitochondrial retrograde (RTG) signaling pathway. Our results show that Slm35 modulates mitophagy through the RTG pathway, independently of Atg32 proteolytic processing by Yme1 or mitochondrial membrane potential dissipation. Notably, Slm35 is crucial for the dynamic regulation of the RTG pathway in mitophagy-inducing conditions. These findings highlight the importance of Slm35 in fine-tuning mitochondrial quality control in response to metabolic cues and suggest a critical role for dynamic RTG pathway regulation in mitophagy control.
