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
backgroundHypertrophic-scar (HS) is the most common pathological healing phenomenon after trauma, especially after deep burns. We aimed to investigate the expression and role of microRNA-211-5p (miR-211-5p) in HS and explore its underlying mechanism.
methodsQuantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-211-5p in 15 cases of HS tissues and normal skin tissues, as well as its expression in human hypertrophic scar fibroblasts (hHSFs) and normal fibroblasts. At the same time, the cell counting kit-8 (CCK-8), scratch test, cell invasion test, and flow cytometry were used to determine cell proliferation, migration, invasion, and apoptosis, respectively. Western blot assay was used to determine the expression of proteins. TargetScan was performed to predict the potential binding sites between miR-211-5p and TGFβR2, which was then verified by western blotting and luciferase reporter gene experiments. Also, co-transfection of plasmids that overexpress miR-211-5p and TGFβR2 were used to observe the reversal effect of miR-211-5p.
resultsThe level of miR-211-5p in HS tissues and hHSFs cells was significantly down-regulated (both P<0.05). The TGFβR2/Smad3 signaling pathway was activated (both P<0.05). Furthermore, the overexpression of miR-211-5p could inhibit the proliferation (P<0.05), migration (P<0.05), and invasion (P<0.05) of hHSFs cells, and induce their apoptosis (P<0.05), and could also regulate the expression of related proteins (all P<0.05). Moreover, the overexpression of miR-211-5p could also inhibit the accumulation of ECM and the activation of the TGF-βR2/Smad3 pathway (all P<0.05), while the opposite effect (all P<0.05) was observed when the level of miR-211-5p was interfered with. Finally, it was confirmed that miR-211-5p could target TGFβR2 (all P<0.05), and when hHSFs cells simultaneously overexpressed miR-211-5p and TGFβR2, the promotion effect of TGFβR2 on cells was reversed by miR-211-5p (all P<0.05).
conclusionsmiR-211-5p can inhibit the activation of the TGF-βR2/Smad3 signaling pathway by targeting TGFβR2, thereby suppressing the proliferation, migration, invasion, and ECM production of hHSFs, and inducing their apoptosis, suggesting that miR-211-5p can become a potential target for the treatment of HS.
