High level of endostatin in epididymal epithelium: protection against primary malignancies in this organ?
Article in Histochemistry and cell biology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Rete testis and epididymis are rare locations for primary tumors or metastasis. Assuming that this may be related to expression level of angiogenic inhibitors, we focused our study on the expression pattern of collagen 18/endostatin. In situ hybridization and immunohistochemistry for collagen 18 and endostatin were carried out on sections of human rete testis and epididymis as well as on epididymal adenoma and human testicular tissue with or without carcinoma in situ (CIS). In situ hybridization revealed strong expression of collagen 18 mRNA in rete testis, efferent ducts and epididymal duct. Immunostaining showed collagen 18 in epithelium and basement membrane as well as in blood vessels of rete testis. Further, in both efferent ducts and epididymal duct, collagen 18 was mainly localized in the basement membrane of these ducts and of the blood vessel wall. Endostatin immunostaining was localized in the epithelium of rete testis, efferent ducts and epididymal duct. This pattern of endostatin staining was absent in epididymal adenoma tissue while tumor associated blood vessels exhibited strong endostatin staining. No endostatin staining was detectable in normal germinal epithelium and CIS cells while Leydig cells exhibited strong endostatin staining. High endostatin expression in epididymis may protect this organ against tumor development. Gene therapeutic strategies providing high expression of endostatin in normal epithelia may be useful to prevent tumor development.
