Only results with raw p-values ≤ 0.05 are shown. aCoefficients show the difference in percentage in the outcome with 10% increases in cytokine ratios. It was calculated as (1.10^beta-1) × 100 and beta was obtained in multivariable regression models adjusted by age (log10-transformed) and technical batch with cytokine ratios (log10-transformed) as predictor variable and birth outcomes as dependent variable. Birth weight and gestational age were log10-transformed. bRaw p-value. cSignificance was established at a Benjamini–Hochberg (BH) adjusted p-value ≤ 0.3. P-values were adjusted by a total of 252 tests performed for each independent variable.
