Correlation between vitamin A, D, E, and K levels in children with allergic rhinitis: a propensity-matched analysis.
Article in BMC pediatrics, 2025. 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
backgroundThe effect of vitamins on children with allergic rhinitis (AR) has been controversial. The correlation between the serum levels of vitamins A, D, E, and K and AR in children needs to be explored.
methodsTwo hundred and eight children with AR (experimental group) and 239 healthy children (control group) were randomly selected from the Pediatric Clinic of Zhejiang Provincial People's Hospital between January 2021 and October 2023. Blood samples were drawn to measure the levels of vitamins A, D, E, and K. Five baseline parameters (gender, age, height, weight, and BMI) were measured in the two sets of data for the propensity score and were matched in a 1:1 ratio to obtain 180 groups.
resultsThe serum vitamin A [Md (IQR):359.50 (295.06,415.26)ng/mL] content of children in the AR group was generally lower than that in the control group, and the serum vitamin K [Md (IQR):0.75 (0.4,1.19)ng/mL] content was generally higher than that in the control group. The differences between the two groups with respect to the levels of vitamins A and K were statistically significant (P < 0.05). In contrast, the differences in the levels of vitamins D and E between the two groups were not statistically significant (P > 0.05). The levels of vitamins A, D, E, and K in both groups were within normal ranges.
conclusionThe vitamin A content in children with AR was lower than that in the control group, whereas the vitamin K content was higher. The correlation between the levels of vitamins D and E and AR in children needs further investigation.
