Descriptive statistics of the antibody ELISA for samples per month and serotype. Box-and-whisker diagram of the measured optical density percent (ODP) per month
and serotype. Showing the smallest observation, lower quartile (Q1), median, upper
quartile (Q3), and largest observation. In addition outliers according their interquartile
range (IQR) and means are displayed. Each circle represents the measured ODP of a
sample. The red line represents the threshold for each serotype, i.e. samples are
considered negative if the ODP is for O >= 50, for A >= 45, for Asia 1 >= 35 and for
C >= 35.
