Lutein levels in arterial cord blood correlate with neurotrophic calcium binding S100B protein in healthy preterm and term newborns.
Article in Italian journal of pediatrics, 2022. 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
backgroundS100B is an established biomarker of brain development and damage. Lutein (LT) is a naturally occurring xanthophyll carotenoid mainly concentrated in the central nervous system (CNS), but its neurotrophic role is still debated. We investigated whether LT cord blood concentrations correlate with S100B in a cohort of preterm and term healthy newborns.
methodsWe conducted a prospective study on the distribution of LT and S100B in arterial cord blood of healthy preterm (n = 50) and term (n = 50) newborns.
resultsS100B and LT showed a pattern of concentration characterized by higher levels (P < 0.01, for all) at 33-36 weeks gestation (GA) followed by a progressive decrease (P < 0.01, for all) from 37 onwards with a dip at term. Both S100B and LT were gender-dependent with significantly (P < 0.01, for all) higher levels in females in preterm and term groups. S100B (R = 0.68; P < 0.001) and LT (R = 0.40; P = 0.005) correlated with GA at sampling. A positive significant correlation (R = 0.87; P < 0.001) between S100B and LT was found.
conclusionsThe present data showing a correlation between S100B and LT supports the notion of a LT trophic role in the CNS. Further investigations in high-risk infants are needed to elucidate LT involvement in the pathophysiological cascade of events leading to CNS development and damage.
