Classification tree showing the factors, which at each node level, had the strongest association with the primary outcome, i.e. a dispensed prescription of Flucloxacillin and/or Clindamycin (“Antibiotics”) within the first 8 weeks following surgical treatment of a distal radius fracture (DRF). The percentage in each box represents the proportion of patients with the primary outcome. P-values were < 0.001 at all nodes and adjusted according to Bonferroni
