WT1 protein expression in astrocytic tumors and its relationship with cellular proliferation index.
Article in Advanced biomedical research, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundAlthough Wilms' tumor gene (WT1) was initially known as a tumor marker in Wilms' tumor, nowadays its role is well known in other sorts of malignancy. This study aimed to evaluate WT1 protein expression levels and its association with cellular proliferation in astrocytic brain tumors by immunohistochemical methods. MATERIALS AND
methodsThis cross-sectional study performed on 73 randomly selected archived tissue samples of astrocytic brain tumors. Sections were observed after immunohistochemical staining regarding WT1 protein expression and MIB-1 staining index. Tumors were classified based on World Health Organization grading system.
resultsWT1 protein expression was seen in the majority of samples (97.3%) with significantly higher index in high-grade tumors (P<0.001). MIB-1 staining index was also significantly higher in high-grade tumors (P<0.001). Moreover, a significantly positive correlation was found between WT1 protein expression and MIB-1 staining index (r: 0.64, P<0.001).
conclusionAstrocytic brain tumors express WT1 protein. It was also found that high-grade tumors are accompanied with higher WT1 protein expression, which is correlated with MIB-1 staining index. WT1 can be used as a marker of malignant cell proliferation and diagnostic tool to differentiate normal astrocytes from neoplastic cells.
