Anemia in children with congenital heart disease and its association with postoperative prognosis.
Article in Italian journal of pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis study aimed to investigate the prevalence and influencing factors of preoperative anaemia in Chinese children with congenital heart disease (CHD), as well as its implications for clinical management and postoperative outcomes.
methodsA cross-sectional study was performed using a pediatric CHD database from Central China. We calculated the prevalence and proportion of anaemia in different subgroups and genders. A visualization of the distribution of hemoglobin in males and females of different age groups was then plotted. Multivariate logistic regression model and forest plots were used to identify influencing factors (presenting odds ratios [OR] and 95% confidence intervals [CI]), and the relationship between preoperative anaemia and postoperative prognosis was evaluated.
resultsA total of 12,294 CHD patients were included, with an overall anaemia prevalence of 41.5%. The neonate was the most critical period (52.5% prevalence), and higher rates were observed in complex CHD (47.2%), low birth weight (LBW, 69.1%), and rural patients (45.3% vs. 37.1% in urban areas). Double-outlet right ventricle (DORV) was most strongly associated with anaemia. Median hemoglobin levels in both genders were below age-specific standards. Preoperative anemia was associated with adverse postoperative outcomes.
conclusionsPreoperative anaemia is highly prevalent in Chinese CHD children, particularly in high-risk subgroups. These findings emphasize the clinical necessity of early screening and targeted intervention to improve postoperative outcomes and quality of life. Future prospective longitudinal studies are warranted to comprehensively elucidate the long-term association between anaemia and CHD across the lifespan.
