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

objectivesWhile smoking is associated with worse outcomes in HPV-positive oropharyngeal squamous cell carcinoma (OPSCC), the magnitude of this association is unclear given the heterogenous smoking definitions and outcomes. Our objective was to investigate the association between smoking, survival, and recurrence in HPV-related OPSCC using multiple smoking metrics reported in the literature. MATERIALS AND

methodsThis was a retrospective cohort study of 375 adults with p16+ OPSCC undergoing surgical resection (n = 272) or definitive chemoradiation (n = 103) at a tertiary academic institution from 2006 to 2017. The primary outcome was overall survival (OS). Secondary outcomes included disease-free survival (DFS), disease-specific survival (DSS), and recurrence. We used multiple smoking metrics commonly cited in previous studies, including ever versus never smokers, current versus former/never smokers, ≤10 versus >10 pack-year, ≤20 versus >20 pack-year, and continuous pack-year.

resultsThere were 375 patients, median age 58 years, with 326 (87%) males, and median follow-up of 52 months. Of all smoking metrics, >20 pack-year history was the strongest predictor of both OS (HR 2.24, 95% CI: 1.19-4.20) and DFS (HR 1.67, 95% CI: 1.04-2.66) on univariable and multivariable analysis after adjusting for age, overall stage, and comorbidities. Patients with >20 pack-year smoking history were also more likely to have recurrence (HR 1.59, 95% CI: 0.95-2.67) after adjusting for overall stage.

conclusionHeavier smoking >20 pack-years was the strongest smoking metric associated with 2-times worse survival and recurrence. Our findings suggest that >20 pack-year smoking history may be a more useful cutoff for risk stratification models but requires further validation.
