Correlation between the umbilical artery pH (UA-pH) and each parameter: a DV-PI, b z-score of DV-S/D, C z-score of TV-S/D, and d z-score of MV-S/D. The values of GA at exam ≤28 + 6 weeks, and GA at exam > 28 + 6 weeks were indicated as ● and 〇, respectively. Solid lines indicate the regression line for the value of ≤28 + 6 weeks cases and dotted lines indicate the regression line for the value of > 28 + 6 weeks cases. a solid line; y = − 0.2085x + 7.4548, dotted line; y = − 0.0835x + 7.2797, b solid line; y = 0.1481x + 7.586, dotted line; y = 0.0637x + 7.2807, c solid line; y = 0.0389x + 7.2758, dotted line; y = 0.0157x + 7.2101, d solid line; y = − 0.0208x + 7.1900, dotted line; y = 0.0297x + 7.2155
