Impact of family socio-economic status on the prognosis of heart transplantation in children.
Article in BMC public health, 2025. 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
backgroundLow family socio-economic status is a known factor that can contribute to increased mortality for patients with cardiovascular disease. However, in developing countries, the prognostic impact of socio-economic level on pediatric HTx is unclear.
methodsWe conducted a retrospective cohort analysis of children younger than 18 years who underwent heart transplantation (HTx) at our center from October 1, 2005, to May 31, 2023. To assess the impact of socio-economic status, we followed up with the discharged children until September 30, 2023, monitoring for all-cause mortality and unplanned readmission events. To evaluate the relationship between socio-economic status and prognosis, we assigned a composite score based on an assessment of household income, parental education level, and occupation. The Cox proportional hazards model and the Kaplan-Meier method were utilized for this analysis.
results64 children (median age at operation 14 years, IQR 13-15) were enrolled and one case died in hospital due to primary graft dysfunction, 63 (98.4%) children had a median follow-up of 60 months (IQR 5.9-113.9). During the follow-up period, 10 (15.9%) children died, and 20 (31.7%) children had 25 unplanned readmissions. Children had higher all-cause mortality and more unplanned readmissions in families with low socio-economic status (n = 33) than middle (n = 10) or high (n = 20) family socio-economic status. Hazard ratios were 5.99,(95%CI:2.28-10.64, P = 0.003) for all-cause mortality for low versus high family socio-economic status, and 2.53 (95%CI:1.04-9.43, P = 0.029) for middle versus high family socio-economic status.
conclusionsLower family socio-economic status is associated with a worse prognosis than high family socio-economic status. Measures to alleviate economic disparities are needed to improve the prognosis of pediatric HTx.
