Examining racial disparities in colon cancer clinical delay in the Colon Cancer Patterns of Care in Chicago study.

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
purposeWe explored a potential racial disparity in clinical delay among non-Hispanic (nH) Black and White colon cancer patients and examined factors that might account for the observed disparity.
methodsPatients aged 30-79 years with a newly diagnosed colon cancer from 2010 to 2014 (n = 386) were recruited from a diverse sample of nine public, private, and academic hospitals in and around Chicago. Prolonged clinical delay was defined as 60 days or more or 90 days or more between medical presentation (symptoms or a screen-detected lesion) and treatment initiation (surgery or chemotherapy). Multivariable logistic regression with model-based standardization was used to estimate the disparity as a difference in prevalence of prolonged delay by race.
resultsPrevalence of delay in excess of 60 days was 12 percentage points (95% confidence interval: 2%, 22%) higher among nH Blacks versus Whites after adjusting for age, facility, and county of residence. Travel burden (time and distance traveled from residence to facility) explained roughly one-third of the disparity (33%, P = .05), individual and area-level socioeconomic status measures explained roughly one-half (51%, P = .21), and socioeconomic measures together with travel burden explained roughly four-fifths (79%, P = .08).
conclusionsLow socioeconomic status and increased travel burden are barriers to care disproportionately experienced by nH Black colon cancer patients.
