Effect of irradiance and delivery configuration on phototherapy efficacy in preterm infants: a network meta-analysis and meta-regression of randomized trials.
Synthesis in BMC pediatrics, 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
backgroundTo compare the effectiveness and safety of different phototherapy strategies in preterm infants using a network meta-analysis of randomized controlled trials, and to explore whether treatment and population-level characteristics modify the rate of bilirubin decline.
methodsWe performed a systematic review and frequentist random-effects network meta-analysis of randomized controlled trials enrolling preterm infants (< 37 weeks' gestation). Phototherapy interventions were grouped based on light source and delivery configuration. Prespecified network meta-regression analyses were conducted to explore potential effect modification by irradiance intensity, delivery configuration, gestational age, birth weight, and baseline bilirubin. The primary outcome was rate of total serum bilirubin decline within 24 h of treatment initiation. This network meta-analysis was prospectively registered in PROSPERO (CRD420261307223).
resultsTwenty randomized trials were included. Double surface phototherapy led to increased TSB reduction (mean difference 0.17 mg/dl/h, 95% CI 0.11-0.22). Higher irradiance strategies demonstrated greater point estimates, although most pairwise comparisons did not reach statistical significance. Meta-regression did not identify statistically significant effect modification, but effect directions were consistent.
conclusionsIn preterm infants, phototherapy efficacy appears to be more closely related to irradiance intensity and exposed body surface area than to device category alone. CLINICAL TRIAL NUMBER: Not applicable.
