Early intramyocardial implantation of exogenous mitochondria effectively preserved left ventricular function in doxorubicin-induced dilated cardiomyopathy rat.
Article in American journal of translational research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
This study tested the hypothesis that early implantation of mitochondria (Mito) into left myocardium could effectively protect heart against doxorubicin/12 mg/kg-induced dilated cardiomyopathy (DCM) in rat. Adult-male SD rats (n = 18) were equally categorized into group 1 (sham control), group 2 (DCM) and group 3 [DCM + Mito (500 μg/rat intramyocardial injection by day-21 after DCM induction)] and euthanized by day 60. In vitro studies showed that exogenously-transferred Mito was abundantly identified in H9C2 cells. The q-PCR showed significant increase in relative number of mitDNA in Mito-transferred H9C2 cells than in control group (P<0.001). The mRNA-gene and protein expressions of NRF1/NRF2/Tfam/PGC-1α/ERRα/Mfn2 were significantly increased in low-dose Mito-transferred and more significantly increased in high-dose Mito-transferred H29C2 cells than in control group (all P<0.01). Day-60 left-ventricular-ejection-fraction (LVEF) was significantly lower in group 2 than in groups 1 and 3, and significantly lower in group 3 than in group 1 (P<0.0001). The ratios of lung and heart weights to tibial length and myocardial histopathological findings of fibrotic area/myocardial injured score/γ-H2AX+ cells exhibited an opposite pattern to LVEF among the three groups (all P<0.0001). The myocardial protein expressions of oxidative-stress (NOX-1/NOX-2/oxidized protein/p22phox), autophagic (beclin-1/Atg-5/ratio of CL3B-II/CL3B-I), and apoptotic/mitochondrial-damaged (cleaved-caspase-3/mitochondrial Bax/cleaved-PARP/cytosolic-cytochrome-C/DRP1/cyclophilin D1) biomarkers exhibited an opposite pattern, whereas the protein expressions of mitochondrial integrity (mitochondrial-cytochrome-C/mitochondrial-complex I/II/III/IV and Mfn2/PGC-1) exhibited an identical pattern to LVEF among the groups (all P<0.001). In conclusion, early Mito therapy effectively preserved LVEF and myocardial integrity in DCM rat.
