[Preliminary Study on the Effect of Adipocytes on the Biological Behaviors of Lung Adenocarcinoma A549 Cells in Tumor Microenvironment].
Article in Zhongguo fei ai za zhi = Chinese journal of lung cancer, 2018. 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
backgroundAdipocytes in the tumor microenvironment may provide the metabolic fuel or signal transduction through media and other means to promote a variety of malignant proliferation and invasion, of tumor cells, but their role in lung cancer progression is still unclear. The purpose of this study was to investigate the effect of adipocytes on lung cancer cell biology.
methods3T3-L1 pre-adipocytes were induced into mature adipocytes. The cell morphology was observed by microscopy and Oil Red O staining. MTT assay, colony formation assay, wound-healing and Transwell methods were used to detect lung cancer cell proliferation, migration and invasion ability. The content of triglyceride in cells was determined by colorimetry.
resultsThe morphology of lung adenocarcinoma A549 cells became more slender after co-culture with mature adipocytes, and the proliferation and cloning ability were significantly enhanced (P<0.05). In addition, mature adipocytes can also promote the migration ability (P<0.05), invasion ability (P<0.01) and accumulation of intracellular lipid (P<0.05) of A549 cells.
conclusionsThese findings suggested that adipocytes in tumor microenvironment can promote the proliferation, migration and invasion of lung adenocarcinoma A549 cells, which may be related to lipid metabolism.
