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
Approximately 50-70 % of patients with retroperitoneal or intraabdominal sarcoma develop a relapse after surgical therapy, including peritoneal sarcomatosis, an extremely rare site of metastatic disease which is associated with an extremely poor prognosis. Accordingly, the establishment of a permanent cell line derived from peritoneal sarcomatosis might provide a helpful tool to understand the biological behavior and to develop new therapeutic strategies. Thus, we established and characterized a liposarcoma cell line (Lipo-DUE1) from a peritoneal sarcomatosis that was permanently cultured without showing any morphological changes. Lipo-DUE1 cells exhibited a spindle-shaped morphology and positive staining for S100. Tumorigenicity was demonstrated in vitro by invasion and migration assays and in vivo by using a subcutaneous xenograft mouse model. In addition, aCGH analysis revealed concordant copy number variations on chromosome 12q in the primary tumor, peritoneal sarcomatosis, and Lipo-DUE1 cells that are commonly observed in liposarcoma. Chemotherapeutic sensitivity assays revealed a pronounced drug-resistant phenotype of Lipo-DUE1 cells to conventionally used chemotherapeutic agents. In conclusion, we describe for the first time the establishment and characterization of a liposarcoma cell line derived from a peritoneal sarcomatosis. Hence, in the future, the newly established cell line Lipo-DUE1 might serve as a useful in vitro and in vivo model to investigate the biological behavior of liposarcoma and to assess novel targeted therapies.
