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
Human epidermal growth factor receptor 2 (HER2) is frequently overexpressed in human ovarian cancers and its overexpression is associated with increased angiogenesis, increased metastasis and reduced survival. Inhibition of HER2 in HER2-overexpressing cancers can lead to reduced angiogenesis and improved survival. Previously, we reported that SV40 T/t-common polypeptide has transcriptional repression activity and can inhibit HER2 expression. In this study, we investigated the effect of T/t-common on the angiogenesis-inducing activity of HER2-overexpressing human SK-OV-3 ovarian cancer cells. We found that compared to conditioned medium from control SK-OV-3 cancer cells, conditioned medium from T/t-common-expressing SK-OV-3 cells had a reduced ability to induce endothelial cell migration and tube formation in vitro and microvessel formation in vivo. These data indicate that T/t-common can inhibit the ability of SK-OV-3 cancer cells to induce angiogenesis. T/t-common was found to be able to downregulate the expression of several proangiogenic factors, including vascular endothelial growth factor-A, interleukin-8, basic fibroblast growth factor, matrix metalloproteinase-2 and urokinase-type plasminogen activator, and upregulate antiangiogenic factors, including thrombospondin-1 and tissue inhibitor of metalloproteinases-1 in SK-OV-3 cancer cells. Finally, we demonstrated that T/t-common could inhibit the angiogenesis and growth of HER2-overexpressing human ovarian tumor in NOD/SCID mice. Taken together, the data suggest that T/t-common had the potential to be developed as a new antiangiogenic agent specific for treating HER2-overexpressing ovarian cancers.
