Impact of duration of delayed umbilical cord clamping on days of phototherapy in preterm neonates 23-35 weeks gestation-a retrospective, single-center cohort study.
Article 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. 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
objectiveTo evaluate whether delayed cord clamping (DCC) duration predicts hyperbilirubinemia and phototherapy days among preterm infants of different gestational ages. STUDY
designIn this retrospective cohort study, 2421 preterm infants inborn at Magee-Womens Hospital 2018-22 were stratified into 3 cohorts: <27wks (n = 206), 27-30 6/7wks (n = 464), and 31-34 6/7wks (n = 1751). DCC duration was assessed in 15 s intervals (0, 15, 30, 45, 60, >65 s). Bivariable analysis and multivariable regression assessed variables associated with phototherapy days.
resultsDCC occurred in 30%, 44%, and 63% of the cohorts, respectively. In bivariable analysis, DCC was associated with higher hemoglobin, peak bilirubin, and phototherapy days for the 31-34 6/7wk cohort only. DCC duration did not predict phototherapy days in adjusted multivariable analysis.
conclusionLonger durations of DCC are not associated with increased phototherapy days in preterm neonates, supporting DCC safety and emphasizing the need to address barriers to consistent implementation.
