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

backgroundIn the general US population, blacks and whites have been shown to undergo colon cancer treatment at disproportionate rates. Accessibility to medical care may be the most important factor influencing differences in colon cancer treatment rates among whites and blacks.

objectiveWe assessed whether racial disparities in colon cancer surgery and chemotherapy existed in an equal-access health care system. In addition, we sought to examine whether racial differences varied according to demographic and tumor characteristics. DESIGN AND

settingDatabase research using the Department of Defense Military Health System. PATIENTS: Patients included 2560 non-Hispanic whites (NHW) and non-Hispanic blacks (NHB) with colon cancer diagnosed from 1998 to 2007.

main outcome measuresLogistic regression was used to assess the associations between race and the receipt of colon cancer surgery or chemotherapy while controlling for available potential confounders, both overall and stratified by age at diagnosis, sex, and tumor stage.

resultsAfter multivariate adjustment, the odds of receiving colon cancer surgery or chemotherapy for NHBs versus NHWs were similar (OR, 0.75 [95% CI, 0.37-1.53]; OR, 0.79 [95% CI, 0.59-1.04]). In addition, no effect modifications by age at diagnosis, sex, and tumor stage were observed. LIMITATIONS: Treatment data might not be complete for beneficiaries who also had non-Department of Defense health insurance.

conclusionsWhen access to medical care is equal, racial disparities in the provision of colon cancer surgery and chemotherapy were not apparent. Thus, it is possible that the inequalities in access to care play a major role in the racial disparities seen in colon cancer treatment in the general population.
