Figure 2.
Box-and-Whisker plot comparing the score of the Neonatal Sepsis Calculator (NSC) in three groups: all infants in the study (median score = 0.02; IQR 0.02), infants receiving antibiotics as per NSC (median = 0.86; IQR = 1.22) and infants recommended antibiotics by Serial Clinical Observation (SCO) (median = 0.86; IQR = 1.22). The score in the study population was low; infants recommended antibiotics as per SCO had higher scores compared with infants recommended antibiotics as per NSC. Each box bounds the IQR range divided by the median (solid horizontal line); the lower and upper margins of the box represent the 25th and the 75th centile, respectively. The whiskers extend 1.5 times the IQR from the median. A circle (o) is used to mark outliers with values between 1.5 and 3 box lengths from the upper edge of the box; the asterisk (*) is used for extreme outliers (a value more than 3 times the interquartile range).
