Effect of Thyroxine on the Structural and Dynamic Features of Cardiac Mitochondria and Mitophagy in Rats.
Article in Cells, 2023. 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
This work investigated the effect of thyroxine on the biogenesis and quality control system in rat heart mitochondria. In hyperthyroid rats, the concentrations of free triiodothyronine and thyroxine increased severalfold, indicating the development of hyperthyroidism in these animals. The electron microscopy showed 58% of cardiac mitochondria to be in a swollen state. Some organelles were damaged and had a reduced number of cristae. Multilamellar bodies formed from cristae/membranes were found in the vacuolated part of the mitochondria. The hyperthyroidism caused no changes to mitochondrial biogenesis in the investigated animals. At the same time, the levels of mitochondrial dynamics proteins OPA1 and Drp1 increased in the hyperthyroid rats. The administration of thyroxine to the animals led to a decrease in the amount of PINK1 and Parkin in heart tissue. The data suggest that excess thyroid hormones lead to changes in mitochondrial dynamics and impair Parkin-dependent mitophagy in hyperthyroid rat heart.
