The collected data were examined by SPSS (v.26). After testing the data normality, Mann Whitney U and Chi-square test were used to compare the quantitative and qualitative variables in the two groups [19]. The correlations between the studied continuous variables were tested by Spearman coefficient (rho) [20]. The receiver operating characteristic curve (ROC) was performed to assess the variables’ ability to differentiate neonates with NRDS from healthy neonates [21]. p-Value ≤ 0.05 was adjudged to be statistically significant [19].
