Phototherapy exposure variability in extremely preterm neonates due to different treatment protocols and devices: cross-sectional study.
Observational study in Journal of perinatology : official journal of the California Perinatal Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo investigate the phototherapy exposure in extremely preterm infants using different treatment protocols and devices.
designCross-sectional observational study enrolling extremely preterm infants requiring light emitting diodes (LED) phototherapy during the first week of life. The duration of phototherapy applying various expert opinion-based treatment guidelines was calculated. Irradiance was measured, and spectral power was estimated.
resultsForty-two preterm infants were studied. The phototherapy duration changed depending on the treatment protocol (overall p < 0.001) and ranged from 0 to 72 h, with a median coefficient of variation of 66.6 [44-124]%. The spectral power was significantly different depending on the LED device (overall p < 0.001) and ranged from 8.6 to 17.8 mW/nm, with a median coefficient of variation of 18.1 [18-18.3]%
conclusionsThe phototherapy exposure of preterm infants significantly varies both as cumulative duration of therapy and spectral power, due to different treatment protocols and devices.
