Double-blind, non-inferiority, randomized controlled trial of dexamethasone 4, 5 and 6 mg for preventing adverse neonatal and maternal outcomes in very preterm to late preterm pregnancies between 29
Article in Reproductive health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPremature birth poses significant health challenges, including respiratory distress syndrome (RDS). Corticosteroids reduce the incidence of RDS, but higher dexamethasone doses may lead to adverse neonatal outcomes, such as growth restriction and neurodevelopmental issues. Determining the appropriate dose is crucial to balance efficacy and safety. Dexamethasone is inexpensive and widely available in most low- and middle-income countries. This study aims to compare the efficacy and safety of 4-mg, 5-mg and 6-mg dexamethasone in preventing RDS among preterm infants. This trial aims to determine whether lower dexamethasone doses are as effective as the standard dose in preventing RDS in preterm infants. By assessing efficacy and potential adverse outcomes, this study will provide critical insights for optimizing treatment protocols and improving neonatal care.
methodsThis randomized controlled trial will include pregnant women with gestational ages between 29
resultsThe study requires 1,560 participants, accounting for a 15% loss to follow-up. The data will be analysed via descriptive statistics, chi-squared tests for categorical data, and one-way ANOVA or Kruskal-Wallis tests for continuous data. An independent Data Safety Monitoring Board will conduct interim analyses every 3 months to ensure participant safety and study integrity. DISCUSSION: This trial addresses the gap in research regarding optimal dexamethasone dosing for preventing RDS in preterm infants. The study will provide evidence on whether lower doses of dexamethasone (4 and 5 mg) are as effective as the standard 6-mg dose and will examine their potential adverse outcomes. The results will guide adjustments to medical practice guidelines, aiming to align them with clinical practices while ensuring safety and efficacy.
