Figure 3From: Preliminary analysis of in utero low-level arsenic exposure and fetal growth using biometric measurements extracted from fetal ultrasound reportsUnadjusted relationship between maternal total urinary arsenic concentration (excluding arsenobetaine) and estimated fetal weight (A), head circumference (B), biparietal head diameter (C), abdominal circumference (D), and femur length (E) Z-score. In all panels, rs represents the Spearman correlation coefficient, black lines represent least squares regression, and dashed line represents LoWeSS (locally weighted scatterplot smoothing) moving average fitted curve.Back to article page
