Histological features of human papilloma virus 16 and its association with the development and progression of anal squamous cell carcinoma.

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
purposeTo investigate the development of anal squamous cell carcinoma (SCC) and the expression patterns of human papillomavirus (HPV).
methodsWe performed typing of HPV-DNA using a polymerase chain reaction (PCR), and amplified the Duchenne muscular dystrophy (DMD) genes simultaneously, to investigate the tumor DNA state. The expression patterns of HPV in the cancer cell nuclei was investigated by in situ hybridization (ISH) using HPV probes.
resultsAmplification of DMD genes was confirmed in 8 of 20 patients with anal SCC, suggesting that tumor DNA was preserved in these patients. In seven of these eight patients, only HPV16 was detected by both PCR and ISH, suggesting HPV16-induced carcinogenesis. In two patients with carcinoma in situ (CIS), the cancer cells showed only a diffuse pattern (DP), and in two patients with invasive cancer, the cancer cell showed only an oligo-dot pattern (OP). In one patient with lesions ranging from CIS to invasive cancer, the histologic features varied in each area, from DP to OP. This change originated in the deep part of the microinvasive area.
conclusionsThese findings show that HPV16 infection is closely involved in the development of anal SCC and suggest that the change in the genome occurs at the stage of microinvasive cancer.
