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

backgroundPatients who travel a long distance (≥50 miles) for cancer care have improved outcomes. However, to the authors' knowledge, the prevalence of long travel distances for treatment by patients with head and neck squamous cell carcinoma (HNSCC), and the effect of travel distance on overall survival (OS), remains unknown.

methodsThe authors used the National Cancer Data base from 2004 through 2013 to identify patients with HNSCC undergoing definitive treatment. Travel distance for treatment was categorized as short (<12.5 miles), intermediate (12.5-49.9 miles), and long (50-249.9 miles). The primary outcome, OS, was evaluated using Cox shared-frailty modeling. A secondary outcome, factors associated with intermediate and long travel distances, was evaluated using multivariable hierarchical logistic regression.

resultsAmong 118,000 patients with HNSCC, 62,753 (53.2%), 40,644 (34.4%), and 14,603 (12.4%) patients, respectively, traveled short, intermediate, and long distances for treatment. After adjusting for relevant covariates, long travel distance was associated with treatment at academic and high-volume centers. Patients of black race, of Hispanic ethnicity, with Medicaid insurance, and who were treated with nonsurgical treatment were less likely to travel long distances for treatment (P<.001). Traveling a long distance for treatment was associated with improved OS on multivariable analysis (adjusted hazard ratio, 0.93; 95% confidence interval, 0.89-0.96) compared with a short distance.

conclusionsTraveling a long distance for HNSCC treatment is associated with improved survival, especially for patients receiving nonsurgical management. Racial and ethnic disparities in travel for HNSCC treatment exist. As regionalization of care continues, future work should identify and address reasons for racial and ethnic disparities in travel that may prevent access to care at high-volume facilities.
