Figure 1

Changes in PCT from birth to 48 h of life in asymptomatic newborns. Box plot comparing serum PCT concentrations in asymptomatic newborns (group 1) at birth, at 12–24 h and 36–48 h of life. The boxes are limited by the 75^th and 25^th percentiles of the data. The middle lines represent the median. Values plotted with cross markers are outside values (more than 1.5 times the interquartile range over 75^th or under 25^th percentiles). Values plotter with plus markers are far out values (more than 3 times the interquartile range over 75^th or under 25^th percentiles).
