Figure 2. Relationships between the fetal plasma cortisol concentration (ng ml⁻¹) and either umbilical glucose uptake (A) or uteroplacental glucose consumption (B).

Uptake expressed in μmol min⁻¹ (kg fetus)⁻¹; y =–0.162x+ 35.374, n = 16, r = 0.52, P < 0.037); consumption expressed in μmol min⁻¹ (kg placenta)⁻¹; y = 4.232x+ 174.520, n = 16, r = 0.60, P < 0.014). Fetuses were infused with either saline (•, n = 8) or cortisol (○, n = 8).
