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

aimsTo investigate the frequency and transcriptional activity of HPV and its correlation to p16 and p21 expression in basaloid squamous cell carcinoma (BSCC) of the larynx.

methodsWe evaluated tissues from 29 patients with BSCC of the larynx for the expressions of p16 and p21 proteins by immunohistochemistry (IHC) and for HPV E6 and E7 mRNA by RNA in situ hybridization (ISH). The presence of genotype-specific HPV DNA was evaluated using PCR-RDB in formalin-fixed paraffin-embedded tissues. P16 and p21 expression and HPV DNA status were correlated with clinicopathological features.

resultsHPV DNA was detected in 8 of 29 (27.59%) patients, with HPV-16 being the predominant genotype. P16 and p21-positivity were observed in 7/29 (24.14%) and 8/29 (27.59%) patients, respectively. HPV was not correlated with p16 expression (

conclusionOur findings suggest that a small fraction of BSCC of the larynx is HPV DNA-positive in this Chinese population, p21 expression was significantly higher in HPV-positive tumors, and no cases were HPV transcriptionally active in this small cohort. Further research of HPV and its role in BSCC of the larynx are warranted.
