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
backgroundTreatment with recombinant human erythropoietin (rHu-EPO) modestly prevented packed red blood cell transfusions (pRBCTs) in preterm infants in studies performed several years ago. In France, some neonatal units stopped using rHu-EPO, while others continued. The aim of this study was to explore the role of rHu-EPO in the prevention of pRBCTs in a recent cohort of preterm infants. MATERIALS AND
methodsPreterm infants who met rHu-EPO indications and were hospitalised between 2018 and 2020 in two neonatal units -one that did not use rHu-EPO and another that did- were eligible. Data about the neonatal history, rHu-EPO and iron treatments and pRBCT indications and volumes were collected. Infants exposed and not exposed to rHu-EPO were compared in univariate and multivariate analyses using backward logistic regression and Cox proportional hazards regression.
resultsA total of 257 patients exposed to rHu-EPO and 285 patients who were not exposed were included. Three profiles emerged. In the infants with a gestational age <28 weeks, the cumulative pRBCT volume/kg was similar regardless of rHu-EPO exposure (mean difference -2.8 mL, 95% confidence interval -16.1, 10.5, p=0.68). In the infants born between 28 and 30 weeks, a late pRBCT was prevented in the rHu-EPO group (single pRBCT: no rHu-EPO 22.1% vs rHu-EPO 8%, p=0.003). However, rHu-EPO was not independently associated with avoidance of this pRBCT. Finally, the need for pRBCT was low in the infants born after 30 weeks of gestation, making rHu-EPO treatment futile. In contrast, early iron supplementation was revealed to be critical in preventing pRBCT. DISCUSSION: No benefit of rHu-EPO in preventing pRBCT was observed in our cohort. The place of rHu-EPO in future requires careful consideration of the population concerned, adjustment of the therapeutic schedule and evolution of the indications for pRBCT.
