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
backgroundPulmonary veno-occlusive disease (PVOD) is a rare subtype of disease that causes pulmonary hypertension with vascular involvement of postcapillary structures of pulmonary vasculature. The disease has a poor prognosis with no effective therapy. The study aimed to determine whether adipose-derived mesenchymal stem cells (ASCs) alleviate pulmonary hypertension and right ventricular hypertrophy in a rat model of PVOD.
methodsAllogeneic ASCs were intravenously administered to a rat model of PVOD induced by mitomycin C. Then, muscularization in pulmonary microvessels, right ventricular systolic pressure (RVSP), and right ventricular hypertrophy were assessed using immunohistochemistry, right heart catheterization, heart weight, and hematoxylin-eosin (HE) staining. Body weight over time and survival rates were assessed.
resultsASC transplantation substantially contributed to the reduction of pulmonary microvascular muscularization in the PVOD rat model but not to the decrease in RVSP. Furthermore, it led to the attenuation of right ventricular hypertrophy and a considerable decrease in wall thickness. However, repeated ASC administration increased the mortality rate in the PVOD rat models.
conclusionsTo the best of our knowledge, this is the first study to analyze the effects of ASC transplantation in a rat model of PVOD. While intravenous ASC transplantation exerts beneficial effects on the lungs and right ventricle, adverse events may occur depending on the administration method. Therefore, intravenous ASC transplantation should be performed with caution.
