[Vitamin D level in umbilical cord blood of late preterm infants and the effect of vitamin D
Trial report in Zhongguo dang dai er ke za zhi = Chinese journal of contemporary pediatrics, 2022. 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
objectivesTo investigate the level of 25 hydroxyvitamin D [25(OH)D] in late preterm infants and the effect of vitamin D
methodsIn this prospective study, 161 late preterm infants who were admitted from June 2017 to June 2020 were enrolled. According to the level of 25(OH)D in umbilical cord blood, they were divided into three groups: sufficiency group (
resultsWithin 24 hours and 3 months after birth, the insufficiency group and the deficiency group had a significantly lower level of 25(OH)D than the sufficiency group (
conclusionsThere is a significant difference in the level of 25(OH)D in umbilical cord blood in late preterm infants. Individualized vitamin D supplementation appears to be more effective for the treatment of vitamin D deficiency. Vitamin D level at birth and in early infancy has certain influence on neurobehavioral development.
