Figure 1From: Association of circulating angiotensin converting enzyme activity with respiratory muscle function in infants Comparison of cACE activity results in relation with ACE genotypes. Comparison of cACE activity results of infants with I/I (n = 18), I/D (n = 52) and D/D (n = 40) ACE genotypes. Box and whisker plot: fine horizontal lines represent 10th, 25th, 50th, 75th and 90th centiles of cACE. Outliers are plotted as discrete data points.Back to article page
