Frequency and Localization of Second Primary Tumors in Patients with Oropharyngeal Carcinoma-The Influence of the Human Papilloma Virus.
Article in Cancers, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeTo investigate the frequency, localization, and survival of second primary tumors (SPT) of oropharyngeal squamous cell carcinoma (OPSCC) depending on human papillomavirus (HPV) status.
methodsWe performed a retrospective chart analysis of 107 OPSCC patients treated at the Zurich University Hospital from 2001 to 2010. Rate and localization of SPT after an index OPSCC were stratified according to smoking and HPV infection status.
resultsIn total, 57/91 (63%) included patients showed an HPV-associated OPSCC. Of these, 37/57 (64.9%) patients with an HPV-positive and 32/34 (94.1%) patients with an HPV-negative OPSCC were smokers. The median age at diagnosis of the SPT was 59.54 years (interquartile range 52.7-65.6). In addition, 8/57 (14%) HPV-positive and 13/34 (38.2%) HPV-negative patients developed SPT. The rate of SPT in patients with HPV-positive index tumors was significantly lower than in patients with HPV-negative OPSCC (
conclusionsPatients with HPV-positive index tumors had a significantly lower risk of developing SPT than patients with HPV-negative tumors. If SPT developed, survival was significantly shorter in patients with HPV-negative tumors than with HPV-positive tumors.
