Article in Zhongguo xiu fu chong jian wai ke za zhi = Zhongguo xiufu chongjian waike zazhi = Chinese journal of reparative and reconstructive surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveTo investigate the effect of microRNA-135a (miR-135a) in human amnion mesenchymal stem cell exosome (hAMSC-Exo) on the migration of fibroblasts.
methodsThe hAMSC-Exo was extracted with exosomes separation kit and identified, the effect of hAMSC-Exo on fibroblasts migration was detected by scratch test. Real-time fluorescence quantitative PCR (qRT-PCR) was used to detect the relative expression of miR-135a gene in hAMSC-Exo after overexpression of miR-135a. Scratch test was used to detect the effect of hAMSC-Exo on the migration of fibroblasts after overexpression and knockdown of miR-135a. Western blot was used to detect the migration related proteins of fibroblasts [large tumor suppressor 2 (LATS2), E-cadherin, N-cadherin, and α smooth muscle actin (α-SMA)] after overexpression and knockdown of miR-135a. The 293T cell exosomes and hAMSC-Exo were used as control.
resultshAMSC-Exos were extracted successfully. Scratch test results showed that hAMSC group had the strongest ability to promote fibroblasts migration, and GW4869 (exosome inhibitor) treatment group had reduced ability to promote fibroblasts migration. qRT-PCR test showed that the relative expression of miR-135a gene in hAMSC-Exo increased significantly after over expression of miR-135a. Scratch test results showed that after over expression of miR-135a, hAMSC-Exo enhanced the migration ability of fibroblasts, while after knockdown of miR-135a, hAMSC-Exo weakened the migration ability of fibroblasts. Western blot results showed that the expressions of E-cadherin, N-cadherin, LATS2 were down regulated and α-SMA was up regulated in each hAMSC-Exo treatment group when compared with 293T cell exosomes group; after over expression of miR-135a, hAMSC-Exo decreased the expressions of E-cadherin, N-cadherin, LATS2 and increased the expression of α-SMA; while after knockdown of miR-135a, the ability of hAMSC-Exo was weakened.
conclusionmiR-135a in hAMSC-Exo can promote fibroblasts' migration, inhibit the expressions of E-cadherin, N-cadherin, LATS2, and promote the expression of α-SMA.
