  • *Incidence rates are reported per 1000 person-years.

  • †Incidence rates were directly standardised to the total US population from the 2010 US Decennial Census after removing the number of people with prevalent multimorbidity (≥3 chronic conditions) as projected from our previous study (see online supplementary table SB).16
