MiRNA-21 Regulates Bronchial Epithelial Cell Proliferation by Activating Tgfβ1/Smad Signaling Pathway and Its Correlation with Asthma Severity in Children.
Article in Iranian journal of public health, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundThis research was designed to probe into the role of miRNA-21 in the pathogenesis of childhood asthma and its correlation with the severity.
methodsFifty-four children with bronchial asthma admitted to the Third Affiliated Hospital of Qiqihar Medical University from Jun 2018 to Dec 2019 were included. Forty nine healthy children underwent physical examination at this time period were also enrolled. The miR-21 expression in peripheral blood serum was analyzed by qRT-PCR. The relationship between the expression and severity of asthma in children was explored by Spearman correlation analysis and ROC curve. Bronchial epithelial cell lines were cultured in vitro and divided into blank control group, negative control group and miR-21 inhibition and activation group. The changes of cell proliferation after treatment were detected by CCK-8 test in different groups. The expression of TGF-β1/Smad signaling pathway protein in cells was assessed by Western blot (WB).
resultsCompared with that of healthy children, the miR-21 expression in peripheral blood serum of asthmatic children was higher (
conclusionmiRNA-21 regulates the proliferation of bronchial epithelial cells by activating TGFβ1/Smad signaling pathway. And it is positively correlated with the severity of asthma in children.
