Cell cycle suppressor proteins are not related to HPV status or clinical outcome in patients with vulvar carcinoma.

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
Interactions between the cyclin-dependent kinase inhibitors (CDKI) and human papillomavirus (HPV) infection in the pathogenesis of vulvar carcinoma are still incomplete. This study aimed to evaluate the prognostic relevance of these proteins in vulvar cancer. One hundred and thirty-nine patient specimens assembled in a tissue microarray were evaluated for p16, p21, p27, and pRb by immunohistochemistry. HPV status was assessed by a linear array HPV genotyping test. In 16 cases with available frozen tumor, quantitative real-time reverse transcriptase-polymerase chain reaction for CDKN2A(p16), CDKN1A, and Rb was performed. Protein expression was considered positive in 40 patients for p16, 35 for p21, 28 for p27, and 19 for pRb. HPV was positive in 43 of the 105 evaluable cases. Expression of CDKIs and pRb, with the exception of p16, seem to be linked to the early phases of vulvar carcinogenesis. Although p16 and p21 protein expression was associated with early stages of disease, no prognostic significance was found when analyzing CDKI proteins or detecting HPV status, limiting their clinical usage. No association was observed between expression of CDKI proteins and HPV status, suggesting that in spite of this association found in cervical cancer, this seems not to be valid for vulvar carcinoma.
