Associations of anaemia and race with peripartum transfusion in three United States datasets.
Article in Blood transfusion = Trasfusione del sangue, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundTransfusion complicates a significant proportion of births in the United States, and Black women have greater prevalence of transfusion at delivery than White women. Antepartum anaemia, a risk factor for peripartum transfusion, is more common among Black women than White women. We aimed to describe the racial distribution of antepartum anaemia in three national datasets and to evaluate the peripartum transfusion rate and characteristics of transfusion recipients, to investigate disparities in haemostatic outcomes. MATERIAL AND
methodsWe performed a retrospective analysis of Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Maternal-Fetal Medicine Units Network Cesarean Registry (CR), NICHD Consortium on Safe Labor Registry (CSL), and a cohort of deliveries at Universal Health Services hospitals (UHS). Univariable associations and multivariable logistic regressions were calculated between race, anaemia and transfusion. Covariates included age, parity, smoking, body mass index, type of insurance, and delivery mode.
resultsWe included n=56,964 deliveries from CR (28% Black), 87,465 from UHS (12% Black), and 140,324 from CSL (24% Black). Anaemia prevalence was 8% in CR, 7% in UHS, and 13% in CSL. Anaemia was more common among Black patients (ORs 2.52, 2.61, and 1.48 respectively) and was associated with transfusion in all databases (ORs 6.46 [95% CI 5.78-7.22]; 5.79 [4.74-7.27]; 1.27 [1.18-1.37] respectively). After adjusting for covariates, Black patients had greater odds of transfusion than non-Black patients in CR (aOR 1.32 [1.16-1.50]), but not in UHS or CSL (aORs 1.19 [0.89-1.59] and 0.40 [0.36-0.44] respectively). DISCUSSION: In our retrospective cohort study using three US registries, we emphasized the link between anaemia and transfusion. Although anaemia was more prevalent among Black patients, the race-transfusion relationship differed between databases, indicating other unexplored factors are involved.
