Association of red blood cell transfusions with periventricular leukomalacia in very preterm infants.
Article in Vox sanguinis, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
objectivesRed blood cell (RBC) transfusions have been associated with retinopathy of prematurity (ROP) and adverse long-term neurodevelopmental outcomes in very preterm infants. Although lower transfusion thresholds reduce the incidence of ROP, they have not improved neurological outcome. Periventricular leukomalacia (PVL) is a major cause of long-term neurodevelopmental impairment in very preterm infants. The objective of this study was to determine whether exposure to RBC transfusions is an independent, dose-dependent risk factor for PVL. MATERIALS AND
methodsA retrospective cohort study was conducted. Infants born at 32 weeks of gestation or less or with a birth weight <1500 g were eligible. Infants transferred from other hospitals, managed with palliative care or who died before cranial imaging were excluded. Exposure was defined as the cumulative number of RBC transfusions during neonatal intensive care. Outcomes were PVL and severe ROP. Multivariable logistic regression analyses were performed and stratified by birth weight <750 g and ≥750 g.
resultsRBC transfusions were independently associated with PVL and ROP. The adjusted odds ratio was 1.10 and 1.09, respectively, in infants weighing <750 g, and 1.26 and 1.15 in infants weighing 750 g or more, respectively, with statistically significant confidence intervals.
conclusionRBC transfusions were independently associated with PVL in preterm infants. As lowering transfusion thresholds has not been associated with improved neurological outcomes, consideration of cord blood products may be warranted.
