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

Human papillomavirus (HPV) is a possible carcinogenetic factor in oral squamous cell carcinoma (OSCC). Previous studies have reported the prevalence of HPV in patients with OSCC. However, the association between HPV and OSCC remains controversial. The present study aimed to clarify the association between HPV infection, p16 protein expression and the clinicopathological characteristics of OSCC. The expression level of HPV-16E6 mRNA and p16 protein, a known surrogate marker of HPV infection, was investigated in 100 OSCC cases using TaqMan reverse transcription-quantitative PCR and immunohistochemistry staining, respectively. HPV-16E6 mRNA expression level was only detected in one case (1%), and positive expression of p16 was found in 10 cases (10%), including an HPV-positive case. Subsequently, the association between p16 expression level and clinicopathological characteristic factors were analyzed; however, no significant association was found. These results suggested that HPV-16 infection was less likely to cause OSCC in Japan and p16 expression was not a suitable marker for HPV infection in OSCC.
