Low expression of secreted frizzled-related protein 4 in aggressive pituitary adenoma.
Article in Pituitary, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
objectiveThe secreted frizzled-related proteins (sFRPs) are reported to be antagonists of a number of tumors. This study was designed to investigate the relationship of sFRP4 with aggressiveness of pituitary adenomas. MATERIAL AND
methodSpecimens were classified into three groups: normal control (n = 10), non-aggressive group (n = 42) and aggressive group (n = 26) according to preoperative magnetic resonance imaging (MRI)/computed tomography. sFRP4 were investigated by PCR, Western blotting, and immunohistochemistry (IHC). The methylation status of the sFRP4 promoter region was observed by MassArray. Cell culture and 5-aza-2-deoxycytidine treatment was performed to observe the relationship of downregulation of sFRP4 with methylation of the sFRP4 gene.
resultsPCR and Western blot results showed that sFRP4 expression was downregulated in aggressive pituitary adenomas, which was confirmed by IHC. Methylation of the sFRP4 promoter was increased in aggressive pituitary adenomas. And methylation of the sFRP4 promoter lead to downregulation of sFRP4 expression.
conclusionssFRP4 expression is inversely related to the aggressiveness of pituitary adenomas, and act as a tumor suppressor.
