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
Background: This study aimed to determine the correlation between maternal third-trimester vitamin A(Vit A)and D levels and neonatal cord blood (CB) concentrations, and to identify modifiable maternal factors influencing neonatal status. Methods: In this cohort of 118 mother-neonate pairs, maternal venous blood levels and CB samples were analyzed. Vit A and 25-hydroxyvitamin D were measured via high-performance liquid chromatography (HPLC) and HPLC coupled with tandem mass spectrometry (HPLC-MS/MS), respectively. Associations were assessed using Pearson correlation and logistic regression. Results: CB Vit A was significantly lower, while CB Vit D was higher than maternal levels (both Conclusions: Neonatal Vit A and D status is positively correlated with maternal third-trimester levels and is associated with specific, modifiable maternal lifestyle and dietary factors, informing targeted prenatal nutritional strategies.
