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
Mitochondria are crucial for the regulation of intracellular energy metabolism, biosynthesis, and cell survival. And studies have demonstrated the role of mitochondria in oxidative stress-induced autophagy in plants. Previous studies found that waterlogging stress can induce the opening of mitochondrial permeability transition pore (mPTP) and the release of cytochrome c in endosperm cells, which proved that mPTP plays an important role in the programmed cell death of endosperm cells under waterlogging stress. This study investigated the effects of the opening of mPTP and the inhibition of ETC on mitophagy in wheat roots under waterlogging stress. The results showed that autophagy related genes in the mitochondria of wheat root cells could respond to waterlogging stress; waterlogging stress led to the degradation of the characteristic proteins cytochrome c and COXII in the mitochondria of root cells. With the prolongation of waterlogging time, the protein degradation degree and the occurrence of mitophagy gradually increased. Under waterlogging stress, exogenous mPTP opening inhibitor CsA inhibited mitophagy in root cells and alleviated mitophagy induced by flooding stress, while exogenous mPTP opening inducer CCCP induced mitophagy in root cells; exogenous mPTP opening inducer CCCP induced mitophagy in root cells. The electron transfer chain inhibitor antimycin A induces mitophagy in wheat root cells and exacerbates mitochondrial degradation. In conclusion, waterlogging stress led to the degradation of mitochondrial characteristic proteins and the occurrence of mitophagy in wheat root cells, and the opening of mPTP and the inhibition of ETC induced the occurrence of mitophagy.
