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
Osteosarcoma is an extremely common primary bone malignancy that is highly metastatic, with most deaths resulting from pulmonary metastases. The extracellular matrix protein thrombospondin-2 (TSP-2) is key to many biological processes, such as inflammation, wound repair and tissue remodelling. However, it is unclear as to what biological role TSP-2 plays in human metastatic osteosarcoma. The immunochemistry analysis from osteosarcoma specimens identified marked up-regulation of TSP-2 in late-stage osteosarcoma. Furthermore, we found that TSP-2 increased the levels of matrix metallopeptidase 9 (MMP-9) expression and thereby increased the migratory potential of human osteosarcoma cells. Osteosarcoma cells pre-treated with an MMP-9 monoclonal antibody (mAb), an MMP-9 inhibitor, or transfected with MMP-9 small interfering RNA (siRNA) reduced the capacity of TSP-2 to potentiate cell migration. TSP-2 treatment activated the PLCβ, PKCα, c-Src and nuclear kappa factor B (NF-κB) signalling pathways, while the specific siRNA, inhibitors and mutants of these cascades reduced TSP-2-induced stimulation of migration activity. Knockdown of TSP-2 expression markedly reduced cell metastasis in cellular and animal experiments. It appears that an interaction between TSP-2 and integrin αvβ3 activates the PLCβ, PKCα and c-Src signalling pathways and subsequently activates NF-κB signalling, increasing MMP-9 expression and stimulating migratory activity amongst human osteosarcoma cells.
