Negative feedback system to maintain cell ROS homeostasis: KEAP1-PGAM5 complex senses mitochondrially generated ROS to induce mitophagy.
Article in Autophagy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
If cellular reactive oxygen species (ROS) production surpasses the intracellular antioxidant capacity, thus altering the ROS homeostasis, the cell needs to eradicate faulty mitochondria responsible for these excessive ROS. We have shown that even moderate ROS production breaks the KEAP1-PGAM5 complex, inhibiting the proteasomal removal of PGAM5. This leads to an accumulation of PGAM5 interfering with PINK1 processing that sensitizes mitochondria to autophagic removal. We propose that such a negative feedback system maintains cell ROS homeostasis.
