Proportions of diagnoses against which antibiotics are recommended based on checkbox data. In each pair of pie charts the larger one represents the proportion of antibiotic recommendations made against either bacterial or non-bacterial problems. The smaller chart breaks down the non-bacterial diagnoses into its subcomponents based the check boxes ticked. Note records that contained more than one check box (indicating multiple problems) are marked with a “+” and this data appears more than once in the chart e.g. a record that had the virus and fungus boxes ticked would appear in the “Virus+” and the “Fungus+” categories. Data from “Insect” and “Mite” check boxes were combined and an isolated record of “Weed” is not represented in the figure
