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

Objective: The average age of patients with vulvar squamous cell carcinoma (SCC) has been reported to have declined. Human papilloma virus (HPV)-related lesions have been shown to be associated with the expression of the immunohistochemical (IHC) marker p16. Non-HPV-related tumors have been characterized by p53 abnormal expression and PDL1 expression. We aimed to evaluate the correlation between these markers and vulvar SCC and to relate it to the clinical and pathological characteristics. Methods: Histopathologic assessments and IHC analyses of p16, p53, and PDL1 were performed in 41 samples of vulvar SCC collected between 2016 and 2021. The data were correlated with clinical and pathological characteristics of the patients. Results: The mean age of the patients was 72.1 years. Positive p16 and PDL1 staining was detected in 24.4% and 17.1% of the samples, respectively. p53 expression was negative in 19.5% of the samples, whereas it was overexpressed in 24.4%. p16-positive tumors showed a smaller depth of invasion (DOI) (p = 0.014), while tumors with p53 abnormal expression showed greater DOI (p = 0.041). PDL1 expression was correlated with increased number of inflammatory cells (p = 0.055). In addition, lesions with lymphovascular space invasion were p16-negative. Conclusion: In our sample, regarding to the SCC incidence the patients' mean age did not change. The expression of p16 was inversely correlated with p53 results. Tumors with p53 abnormal expression and absence of p16 showed a greater DOI. Our data suggest an association between PDL1 expression and increased inflammatory infiltrates in vulvar SCC.
