Gene and protein expression of p53 and p21 in fibroadenomas and adjacent normal mammary tissue.

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
The aim of this study was to compare p53 and p21 mRNA, and proteins levels between fibroadenomas and adjacent normal mammary tissue of women in reproductive age. A transversal study was performed. Fourteen patients who attended the Breast Service of the Hospital de Clínicas de Porto Alegre were assessed and submitted to surgical resection of fibroadenomas. Fragments of the central area of the fibroadenoma and adjacent normal mammary tissue were obtained. mRNA expression for genes p53 and p21 was evaluated by RT-PCR, and protein expression by the western blot. Paired analyses showed higher gene expression of p53 (P = 0.017) and p21 (P = 0.003), and a higher protein expression of p53 (P = 0.001) in fibroadenomas as compared to normal breast tissue. p21 protein expression was not different (P = 0.97) between the fibroadenoma and the adjacent normal mammary tissue samples. These results suggest the participation of p53 in the formation of fibroadenomas. The role of p21 in fibroadenomas remains to be defined.
