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
objectivesHuman Amniotic Mesenchymal Stem Cells (hAMSCs) have strong multidirectional differentiation ability. Studies have found that transfection of target genes into target cells by lentivirus can enhance the differentiation potential of the cells. Angiotensin-Converting Enzyme 2 (ACE2) was found to improve vascular remodeling. Research is lacking on ACE2-hAMSCs. Therefore, this study aimed to investigate the ability to improve pulmonary arterial hypertension using ACE2-hAMSCs.
methodsLentiviruses overexpressing ACE2 were mixed with hAMSCs. Then, ACE2-hAMSCs and hAMSCs with good growth in logarithmic growth phase were collected. We detected their migration and angiogenesis. RT-qPCR technology was used to detect the expression levels of genes related to angiogenesis, and inflammation in the two cell lines, and western-blotting was used to detect the expression levels of ACE2. As an animal study, 21 rats were randomly divided into four different groups. Right heart hypertrophy, pulmonary angiogenesis, and serum inflammatory factors were measured before dissection. H&E staining was used to observe the inflammatory infiltration of lung tissues.
resultsThe migration and angiogenesis of ACE2-hAMSCs were strongerthan that of hAMSCs alone. The expressions of genes in ACE2-hAMSCs were higher, and the expression of ACE2 protein in ACE2-hAMSCs was less. H&E staining showed that the inflammatory infilration of lung tissue in ACE2-hAMSCs groups was significantly improved. In addition, the ACE2-hAMSCs group had stronger pro-angiogenesis and anti-inflammatory effects.
conclusionThese results suggest that ACE2-hAMSCs can repair pulmonary vascular endothelial cell injury caused by pulmonary hypertension by promoting angiogenesis and anti-inflammatory ability. This shows that ACE2-hAMSCs have stronger ability to improve pulmonary vascular remodeling than hAMSCs alone.
