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
In order to systematically evaluate the influence of lymph nodes (LNs) in lymph node metastases (LNM) of hepatocellular carcinoma (HCC), we set up a new in vitro model in which Hca-F and Hca-P cells were cultured in medium containing lymph node homogenates (LNHs). Differential protein expression was measured by two-dimensional gel electrophoresis (2-DE) combined with matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectrometry (MALDI TOF/TOF MS). Results from protein identification revealed two metastatic correlative proteins, 78-kDa glucose-regulated protein (GRP78) and galectin-3 (GAL3). Western blotting confirmed that GRP78, a protein positively correlated with metastasis, increased 2.4-fold in Hca-F cells but decreased to almost a half in Hca-P cells (P<0.05). However, GAL3, a protein negatively correlated with metastasis, was decreased by a half in Hca-F cells but slightly increased non-significantly in Hca-P cells. Thus, our results reveal that some components of LNHs may facilitate a permissive environment for cancer cells with high metastasis potential to eventually metastasize. GRP78 and GAL3 may serve as potential biomarkers for the diagnosis of LNM in HCC.
