Categorical variables are presented as numbers (percentages) [n (%)], and comparisons between groups were performed using the Chi square test. Continuous variables that conform to a normal distribution are represented as mean ± standard deviation (Mean ± SD), and inter group comparisons are conducted using independent sample t-test (Continuous variables conforming to a normal distribution are presented as mean ± standard deviation (Mean ± SD)) SD), and inter-group comparisons were analyzed using the independent samples t-test)。 P<0.05 is considered statistically significant. The use of dietary supplements “is defined as any commercial nutritional supplements beyond normal diet, such as multivitamins, vitamin D, calcium, iron, or omega-3 fatty acids, that are currently regularly consumed outside of normal diet, as reported by the guardians. GDD, Global Developmental Delay; HC, Healthy control group.
