Frequency and genotype of human papillomavirus among Sudanese patients with head and neck tumours.
Article in Ecancermedicalscience, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectivesThe aim of this study was to determine the frequency and genotype of human papillomavirus (HPV) infections in head and neck squamous cell carcinomas (HNSCCs) and benign head and neck tumours. METHODOLOGY: A retrospective study was performed on 150 samples of patients diagnosed with HNSCCs and 50 samples obtained from patients diagnosed with benign head and neck tumours. Tumour DNA was amplified using polymerase chain reaction (PCR) with HPV consensus and multiplex primers.
resultsSix of the 150 (4%) HNSCCs were HPV positive. HPV16 was the most prevalent type, with single infections present in 3/6 (50%) cases, whereas HPV18 and HPV33 were detected in 2/6 (33%) and 1/6 (17%), respectively. HPV infections were detected in 3 (50%) cases of oral cavity and 3 (50%) cases of pharynx.
conclusionsThere was a significant association between HPV infection and HNSCCs (P < 0.05). The present data support the importance of HPV infection in oral and larynx tumours.
