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

backgroundThe purpose of this study was to determine the association between race and long-term cancer outcomes (recurrence and overall survival) within a population of US patients with locoregional colorectal cancer (CRC).

methodsA cohort study of primary patient data merged with the National Cancer Database as part of a Commission on Cancer Special Study was performed. The study population was a random sample of patients undergoing surgery for stage I to III CRC between years 2006 and 2007 with 5 years of follow-up. Propensity-weighted multivariable Cox regression was performed with pooled results to yield statistical inferences. Prespecified sensitivity analysis was performed only for patients who received guideline concordant care (GCC) of primary CRC. All statistical tests were 2-sided.

resultsThe study population included 8176 patients, 9.9% (n = 811) Black and 90.1% (n = 7365) White. Black patients were more likely to be uninsured or underinsured, have lower household income, and lower educational status (all P < .001). Rates of GCC were higher among Black vs White patients with colon cancer (76.9% vs 72.6%, P = .02), and Black and White patients with rectal cancer were treated with radiation at similar rates (69.1% vs 66.6%, P = .64). Black race was independently associated with increased risk of recurrence (hazard ratio [HR] = 1.48, 95% confidence interval [CI] = 1.26 to 1.73) and mortality (HR = 1.37, 95% CI = 1.18 to 1.59). In sensitivity analysis of only patients who received GCC, observed effects for recurrence (HR = 1.51, 95% CI = 1.27 to 1.79) and overall survival (HR = 1.40, 95% CI = 1.18 to 1.66) persisted.

conclusionsDespite higher rates of GCC for CRC, Black patients experience a higher risk of recurrence and mortality compared with White patients.
