1 · What the graph read from it

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.

2 · The registry

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

backgroundThe human papillomavirus (HPV) prevalence in males has been reported to be between 3.6% and 84%, depending specially on the socioeconomic status. HPV infection has been related as a risk factor for penile cancer. This is a rare tumor, and other risk factors include lack of personal hygiene and men who have not undergone circumcision. Penile cancer is less than 1% of cancers in men in the United States, however, is much more common in some parts of Asia, Africa, and South America, where it accounts for up to 10% of cancers in men. This study aimed to determine the prevalence of HPV-DNA in penile cancers in São Luís, Brazil and to correlate the virus presence to histopathological factors.

methodsTumor paraffin samples of 76 patients with penile carcinoma were tested in order to establish the prevalence and distribution of genotypic HPV using PCR/Nested and automated sequencing. To evaluate the association between HPV types and other clinical and morphological variables, a nonparametric ANOVA was performed using a Kruskal Wallis test, and statistical significance was determined to a value of p < 0.05.

resultsThe average age of patients at the time of diagnosis was 66 years ± 17.10. Regarding location, 65.79% of the tumors were located in the glans, and the most common types were vegetative (34.21%) and squamous (98.68%). Most of the lesions ranged in size from 2.1 to 5.0 cm, presenting Jackson I stage and Broders II degree. It was observed that 32 patients had at least one invaded and/or infiltrated structure. Lymph node involvement was observed in 19.76% of the patients, and 21.05% showed an inflammatory process. In the molecular evaluation, HPV infection was observed in 63.15% of the lesions, and the most common type was HPV 16.

conclusionsFrom the statistical analysis, it can be verified that the variables were not associated with infection by the HPV virus. Although penile cancer can result from various risk factors that act in synergy, an HPV virus infection is important for the development of such neoplasm.
