Correlative analysis of plasma adenosine levels in pregnant and non-pregnant women. HPLC was used to measure adenosine levels in plasma samples from non-pregnant (control, n = 30) and pregnant women (NP, n = 30). The adenosine level was correlated with (a) body mass index (BMI) or estimated consumption of (b) polyunsaturated fatty acids (PUFA) or (c) carbohydrates. Significant correlations were only observed with BMI in normal pregnancy (r = 0.39, 95% IC 0.03 to 0.67, p = 0.02) and PUFA consumption in non-pregnant women (r = −0.33, 95% IC −0.61 to 0.03, p = 0.03)
