Human lung cancer-derived microparticles enhanced angiogenesis and growth of hepatoma cells in rodent lung parenchyma.
Article in American journal of translational research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 human lung cancer-derived microparticles (LcD-MPs) played an important role in tumor angiogenesis and growth. Fischer 344 rats (F344, n=18) were equally categorized into group 1 [Sham Control (3.0 mL normal saline intravenous injection (IV))], group 2 [hepatoma cell line (2.0 x 10(6) cells, IV)], and group 3 [hepatoma cell line + LcD-MPs (3.0 x 10(6), IV)]. Animals were euthanized by day 28 after hepatoma cells transfusion. Our result showed that the gross pathology confirmed growth of hepatoma cell line in lung parenchyma. The size and weight of the lungs were significantly increased in group 2 and further elevated in group 3 than in group 1 (all p<0.001). Histopathological analysis demonstrated that the lung crowded score and number of small vessel exhibited an identical pattern, whereas the number of alveolar sacs showed an opposite pattern compared to that of total lung weight among the three groups (all p<0.0001). The cellular expressions of CD34(+), CXCR4(+), c-Kit(+), CK19(+), VEGF(+) and vimentin+ cells in lung parenchyma exhibited an identical pattern compared to those of total lung weight among all groups (all p<0.001). The protein expressions of apoptotic (Bax, cleaved caspase-3 and c-PARP), fibrotic (Smad3, TGF-β), and tumor suppression (PTEN) biomarkers showed an identical pattern, whereas that of anti-apoptotic (Bcl-2) and anti-fibrotic (Smad1/5, BMP-2) biomarkers were displayed an opposite pattern compared to that of total lung weight among all groups (all p<0.001). The MPs could enhance angiogenesis and accelerated hepatoma cell growth in rodent lung parenchyma.
