Human Papillomavirus‒Positive and ‒Negative Vulvar Squamous Cell Carcinoma Are Biologically but Not Clinically Distinct.
Article in The Journal of investigative dermatology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
Vulvar squamous cell carcinoma pathogenesis is traditionally defined by the presence or absence of human papillomavirus (HPV), but the definition of these groups and their molecular characteristics remain ambiguous across studies. In this study, we present a retrospective cohort analysis of 36 patients with invasive vulvar squamous cell carcinoma where HPV status was determined using RNA in situ hybridization and PCR. Clinical annotation, p16 immunohistochemistry, PD-L1 immunohistochemistry, HPV16 circular E7 RNA detection, and RNA sequencing of the cases were performed. A combination of in situ hybridization and PCR identified 20 cases (55.6%) as HPV positive. HPV status did not impact overall survival (hazard ratio: 1.36, 95% confidence interval = 0.307-6.037, P = 0.6857) or progression-free survival (hazard ratio: 1.12, 95% confidence interval = 0.388-3.22, P = 0.8367), and no significant clinical differences were found between the groups. PD-L1 expression did not correlate with HPV status, but increased expression of PD-L1 correlated with worse overall survival. Transcriptomic analyses (n = 23) revealed distinct groups, defined by HPV status, with multiple differentially expressed genes previously implicated in HPV-induced cancers. HPV-positive tumors showed higher global expression of endogenous circular RNAs, including several circular RNAs that have previously been implicated in the pathogenesis of other cancers.
