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

African Americans experience a higher mortality rate and an excess burden of ESRD compared with Caucasians in the general population, but among those treated with dialysis, African Americans typically survive longer than Caucasians. We examined whether differences in inflammation may explain this paradox. We prospectively followed a national cohort of incident dialysis patients in 81 clinics for a median of 3 years (range 4 months to 9.5 years). Among 554 Caucasians and 262 African Americans, we did not detect a significant difference in median CRP between African Americans and Caucasians (3.4 versus 3.9 mg/L). Mortality was significantly lower for African Americans versus Caucasians (34% versus 56% at 5 years); the relative hazard was 0.7 (95% CI, 0.5 to 0.9) after adjusting for age, gender, dialysis modality, smoking, body mass index, diabetes, BP, cholesterol, cardiovascular disease, congestive heart failure, comorbid disease, hemoglobin, albumin, CRP, and IL-6. However, the risk varied by CRP tertile: the relative hazards for African Americans compared with Caucasians were 1.0 (95% CI, 0.7 to 1.4), 0.7 (95% CI, 0.4 to 1.3), and 0.5 (95% CI, 0.3 to 0.8) in the lowest, middle, and highest tertiles, respectively. We obtained similar results when we accounted for transplantation as a competing event, and we examined mortality across tertiles of IL-6. In summary, racial differences in survival among dialysis patients are not present at low levels of inflammation but are large at higher levels. Differences in inflammation may explain, in part, the racial paradox of ESRD survival.
