  1. aResults from nasal swabbing (two samplings with median time interval of 28 days) and spa-typing in the Tromsø 6 study in October 2007–August 2008. S. aureus carriage status as defined by van Belkum et al. [4]
  2. bIncludes both noncarriers and intermittent carriers
  3. cResults from one nasal swab sampling and spa-typing in the present study in 2010–2011; +, positive for S. aureus; −, negative for S. aureus
