Box plots of proportion of survivors with in-hospital sequelae. This figure presents box plots of the range of estimates for any in-hospital neuropsychological sequelae by pathogen and for all causes of confirmed bacterial meningitis (CBM) combined. The upper border of the shaded box is the value of the 75th percentile and the lower border of the shaded box is the 25th percentile, and these two values define the interquartile range (IQR). The vertical 'whiskers' represent the values 1.5 IQRs above the 75th percentile and 1.5 IQRs below the 25th percentile. Any data points that are beyond the whiskers appear as outliers (dots). The median estimate for each group is represented by the horizontal line within the shaded box and the number above the horizontal line.
Spn = Streptococcus pneumoniae, Hib = Haemophilus influenzae type b, Nm = Neiserria meningitidis
