Race, ABO blood group, and venous thromboembolism risk: not black and white.
Article in Transfusion, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 1 of them a synthesis that pooled 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.
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 rate of venous thromboembolism (VTE) has been reported to be higher in blacks compared to whites. Non-O blood groups have also been associated with a significantly higher VTE risk. Given that a higher proportion of blacks have O blood group, one might have expected that black individuals would have fewer VTEs. STUDY DESIGN AND
methodsIn this study, we analyzed race, sex, age, ABO or Rh blood group, and VTE risk in 60,982 black and white patients admitted over a span of 10 years.
resultsThe overall occurrence of VTEs was 7.6%, higher in males (8.7% males vs. 7.2% females), higher in non-O blood groups (8.5% non-O vs. 6.9% O blood group), and increased with age (5.8% <65 years, 11.3% ≥65 years). No difference in VTE rate was noted with Rh antigen positivity. When stratified by age, VTE rate was consistently higher in blacks and non-O blood groups. No difference was detected among the various non-O blood groups. To assess the potential confounder of comorbidities, we stratified patients according to Charlson comorbidity score. In a subgroup of healthy patients with age-independent Charlson comorbidity scores of 0 (n = 28,387), blacks still had an increased VTE risk and this risk was still higher with increasing age and in those with non-O blood groups.
conclusionWe conclude that black race and non-O blood groups have increased VTE risk when stratified for age and that associated comorbidities do not explain these differences.
