Fig. 1From: Normative values for circulating intestinal fatty acid binding protein and calprotectin across gestational agesIntestinal fatty acid binding protein (IFABP, blue line) and calprotectin (red line) levels by gestational age during the first week of life (N = 112). For IFABP, there was a statistical difference but unclear clinical difference between gestational ages (P = 0.039) given overall low levels. For calprotectin, there was a significant difference between gestational ages (P = 0.004), but not a clear patternBack to article page
