Disparity Between Functional and Structural Recovery of Placental Mitochondria After Exposure to Hypoxia.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Intrauterine growth restriction (IUGR) affects 5-10% of pregnancies with placental hypoxia, playing a key role as a common pathophysiological pathway of different etiologies. Despite the high metabolic rate of the placenta and its "gatekeeper" role in protecting the fetus from hypoxia, the response of placental mitochondria to hypoxic stress is not well understood. This study tested the hypothesis that transient exposure to hypoxia leads to a loss of placental mitochondria and affects their function. Human villous trophoblastic (JEG-3) cells were cultured under normoxic and hypoxic conditions for 24 h. Mitochondrial content was determined by flow cytometry before and after hypoxic exposure and after 24 h of normoxic recovery. Parameters of oxidative phosphorylation were assessed using a respirometric analyzer before hypoxic exposure and after normoxic recovery. Mitochondrial content decreased significantly from 88.5% to 26.7% during hypoxic incubation. Although it had increased to 84.2% after 24 h of normoxic recovery, oxidative phosphorylation parameters were still significantly suppressed to 1/2 to 1/3 of the pre-incubation levels. The results underscore the ability of placental cells to adapt mitochondrial content to O
