Fig. 1From: Predicting the serum digoxin concentrations of infants in the neonatal intensive care unit through an artificial neural networkDigoxin volume distribution (Vd), which were normalized by bodyweight versus postmenstrual age (PMA) among all enrolled newborn infants in neonatal intensive care unit (one dose after steady-state; n = 71). Note: the line in the middle is the mean of Vd per total body weight (mean = 5.24 L/kg) and the upper and lower line are the upper and lower limits of 95% confidence interval for the mean Vd, respectively.Back to article page
