Fig. 3From: Normative values for circulating intestinal fatty acid binding protein and calprotectin across gestational agesScatterplot of repeat measures of calprotectin by day of life in the premature longitudinal cohort (N = 19) with a linear fit prediction plot for calprotectin (y) on day of life (x). The calprotectin level decreased by 2% per day of life (P < 0.001); however, the correlation was low (correlation = 0.13)Back to article page
