Limited Evidence of Noradrenaline Use and Effectiveness in Preterm Neonates: A Systematic Review.
Synthesis in Acta paediatrica (Oslo, Norway : 1992), 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
aimThe study aimed to analyse the effects and associated outcomes of noradrenaline in treating hypotension in preterm neonates.
methodsWe searched PubMed, Web of Science, and Scopus to August 2025 for randomised and observational studies on noradrenaline use in preterm neonates. The studies were summarised without statistical pooling.
resultsOf 202 screened abstracts, eight studies (one randomised controlled trial [RCT], seven observational) were included. In total, 340 preterm infants were treated with noradrenaline. Sample sizes ranged from 21 to 70. The risk of bias was low in the RCT and moderate to critical in the observational studies. Mortality was similar in the RCT and lower in one observational study comparing noradrenaline to dopamine, although evidence certainty was very low. Evidence for bronchopulmonary dysplasia, intraventricular haemorrhage, and necrotising enterocolitis was limited and showed no consistent differences between treatments. Noradrenaline consistently increased mean blood pressure within hours, but the effect on heart rate was modest.
conclusionNoradrenaline increases blood pressure and improves perfusion markers in preterm infants with hypotensive shock. However, evidence comparing it with dopamine is limited and of very low certainty. Noradrenaline may be effective, but robust comparative studies are needed to confirm its safety and efficacy, especially in extremely preterm infants.
