Increased expression of EGFR and TGF-alpha in segmental renal dysplasia in duplex kidney.

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
Renal dysplasia (RD) is a disorganised development of renal parenchyma that results in a deficit of functional renal tissue. It is known that the epidermal growth factor (EGF) and the transforming growth factor-alpha (TGF-alpha) enhance renal cell proliferation, migration and differentiation during kidney development through binding to the same EGF receptor (EGFR). The aim of the study was to analyse the expression of TGF-alpha and EGFR in the dysplastic kidney. The specimens of dysplastic upper poles duplex kidneys were surgically resected from 19 patients. Indirect immunohistochemistry was performed using the ABC method employing antibodies against EGFR and TGF-alpha, and gene expression using primers specific to the human genes. There was absent or weak EGFR and TGF-alpha immunoreactivity in normal kidney tissue. In dysplastic kidneys, there was strong TGF-alpha and EGFR immunoreactivity in the epithelium of primitive tubules and strong EGFR immunoreactivity in the connective tissue around the primitive tubules. Our findings of markedly increased local expression of EGFR and TGF-alpha in primitive tubules suggest that EGFR and TGF-alpha may play an important role in altering renal morphogenesis resulting in renal dysplasia.
