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
unlabelledThis study was initiated to investigate the efficacy of myocardial fibrosis intervention via signal transducer and activators of transcription (STAT) signaling using bone marrow (BM) mesenchymal stromal cells (MSC) in which being over-expressed with the aid of bispecific antibody (BiAb) and ultrasound-mediated microbubbles (MB). BiAb was prepared and combined with isolated MSC with CD47 overexpression from male mice and trans-fused into female mice with isoproterenol-induced myocardial fibrosis via the tail vein, followed by MB. This study included five groups. Five weeks after treatment, expression levels of the sex-determining region of Y-chromosome (SRY), matrix metalloproteinases (MMP)-9, tissue inhibitor of metalloproteinase (TIMP)-1 and vascular endothelial growth factor (VEGF) in myocardium were detected by fluorescent quantitative real-time polymerase chain reaction (qRT-PCR). The protein expression of signal transducer and activators of transcription (STAT) 1 and STAT 3 was detected by Western blot.
resultsThe highest homing number of MSC was in the CD47 + MSC + BiAb + MB group, second highest in the CD47 + MSC + BiAb group, and lowest in MSC alone. Compared with the Control group, CD47 + MSC + BiAb + MB, CD47 + MSC + BiAb, CD47 + MSC and MSC groups had decreased levels of MMP-9, TIMP-1, STAT 1 and collagen deposition, and increased levels of STAT 3. Up regulated STAT 3 and down regulated TIMP-1 were significantly different in CD47 + MSC + BiAb + MB compared with CD47 + MSC or CD47 + MSC + BiAb.
conclusionCD47 can enhance the homing rate and repairing efficacy of MSC. MSC can improve MMP-TIMP expression in injured myocardium and interfere with myocardial fibrosis after homing, a mechanism that may be related to the STAT-mediated signaling pathway.
