Beta-blockers and breastfeeding: a real-life prospective study.
Article in European journal of clinical pharmacology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeAt Lille University Hospital, a pregnancy heart team including cardiologists, obstetricians, pediatricians, anesthetists, geneticists, and pharmacologists discusses about treatment compatibility taken during breastfeeding in pregnant women (or those wishing to be pregnant) with complex cardiovascular pathologies. Beta-blockers are among the drug most often used in these patients, and data are missing or suggest a risk to the breastfed child. The aim of this study was to evaluate the proportion of women treated with beta-blockers, identified during the multidisciplinary meeting, who breastfed and to monitor adverse effects (AEs) in newborns.
methodsA prospective descriptive study was conducted from 1 December 2017 to 1 December 2021. All pregnant patients followed up by the pregnancy heart team in Lille University Hospital, treated with beta-blockers and who gave birth, were contacted as part of the pharmacovigilance follow-up.
resultsThe proportion of women treated with beta-blockers intending to breastfeed was 69.8%. Among the 53 women interviewed, 49% did not breastfeed, including 10 because of the theoretical incompatibility of their beta-blocker with breastfeeding. Among the 27 women who breastfed, 30% breastfed while treated with a theoretically incompatible beta-blocker; 56% was changed from their initial beta-blocker to allow safe breastfeeding. No serious AE was observed.
conclusionTo our knowledge, our study is the largest series of patients treated with beta-blockers during breastfeeding. Taking a treatment can be an obstacle to breastfeeding, but for the particular case of beta-blockers, even if the available data are few and sometimes worrying, the data from this study are reassuring.
