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
Myofibroblasts play a critical role in the cancer cell growth, invasion, and tumor-associated vascularization during the carcinogenesis of nonsmall cell lung cancer (NSCLC), whereas the underlying molecular bases are not completely understood. We isolated Lin-negative, Sca1-low, and CD49e-high myofibroblasts from the NSCLC tissues of the patients and modified the levels of either transforming growth factor β 1 (TGFβ1) or vascular endothelial growth factor A (VEGF-A) in these cells. We found that coculture with TGFβ1-overexpressing myofibroblasts significantly decreased the NSCLC cell growth in an MTT assay through proliferation suppression rather than modulation of cell apoptosis, while significantly increased the NSCLC cell invasiveness in either a transwell migration assay or a scratch wound healing migration assay. However, modulation of TGFβ1 levels in myofibroblasts did not significantly alter vessel formation in a human umbilical vein endothelial cells (HUVECs) transwell collagen gel assay. On the other hand, overexpression of VEGF-A in myofibroblasts significantly increased vessel formation in the HUVECs transwell collagen gel assay. Together, these data suggest that myofibroblasts may regulate cancer cell growth and invasion through TGFβ1 but modulate cancer-associated neovascularization through VEGF-A. Hence, targeting different signaling pathways in myofibroblasts may delicately control NSCLC growth and invasion.
