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

Research has shown that black patients more frequently undergo surgery at low-quality hospitals than do white patients. We assessed the extent to which living in racially segregated areas and living in geographic proximity to low-quality hospitals contribute to this disparity. Using national Medicare data for all patients who underwent one of three high-risk surgical procedures in 2005-08, we found that black patients actually tended to live closer to higher-quality hospitals than white patients did but were 25-58 percent more likely than whites to receive surgery at low-quality hospitals. Racial segregation was also a factor, with black patients in the most segregrated areas 41-96 percent more likely than white patients to undergo surgery at low-quality hospitals. To address these disparities, care navigators and public reporting of comparative quality could steer patients and their referring physicians to higher-quality hospitals, while quality improvement efforts could focus on improving outcomes for high-risk surgery at hospitals that disproportionately serve black patients. Unfortunately, existing policies such as pay-for-performance, bundled payments, and nonpayment for adverse events may divert resources and exacerbate these disparities.
