Table 3 Factors associated with a dispensed prescription of Flucloxacillin and/or Clindamycin within 8 weeks following surgery of a distal radius fracture between November 1st 2006 and October 31st 2013 in 31,807 adult Swedish patients. A logistic regression model was performed and results are presented as crude measures and odds ratios in uni- and multivariable analyses
