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
backgroundMitochondrial transplantation (Mito-T) is a novel therapeutic strategy for ischaemic cardiovascular diseases. This study aimed to test the efficacy of human umbilical mesenchymal stem cell-derived mitochondrial transplantation (Mito-T) on preeclampsia (PE).
methodsPE was induced in Sprague-Dawley pregnant rats by infusing angiotensin II (Ang II) starting on gestation day 8 (GD 8). Mito-T (100 μg/μl) was injected via the jugular vein on GD 14.
resultsOn GD 20, PE rats exhibited high blood pressure, kidney and placental vascular abnormalities, reduced placental and foetal weights, foetal crown-rump lengths. Mito-T was predominantly distributed in the kidneys, uterus, and placenta of PE rats. Mito-T reversed clinical manifestations of PE, restored placental vascular abnormalities, and reduced serum sFLT-1 levels and the sFLT-1/PlGF ratio. In placental mitochondria, Mito-T increased protein levels of complexes (I‒V), improved mitochondrial membrane potential, ATP synthase, citrate synthase activities, and biogenesis markers (PGC-1α, TFAM, and NRF1), and reduced reactive oxygen species production. Mito-T increased mitochondrial fusion proteins (OPA1, MFN1, and MFN2) in the placenta, whereas fission (DRP1 and FIS1) and mitophagy (PINK, BNIP3, BNIP3L, and FUNDC1) proteins were reduced. In placental tissue, primary trophoblast cells, and the Bewo cell line, Mito-T reduced the mRNA and protein levels of sFLT-1 and attenuated the calcineurin-NFAT pathways elevated by PE or Ang II.
conclusionsThis study demonstrates that Mito-T reverses the pathological phenotypes of PE rats by improving placental mitochondrial activity and suppressing trophoblast-derived sFLT-1 production. These findings provide proof-of-concept evidence that Mito-T could serve as a potential therapeutic strategy for reducing maternal and foetal risks in patients with PE.
