*No causes of death due to diseases of the sensory organs, skin diseases or pregnancy related diseases were observed in the study population.
**Adjusted for calendar periods and for inpatient admission prior to MD.
***The Danish Register of Causes of Death was complete through 2006. In 2007, 23 MD patients and 62 individuals from the population cohort died and these deaths were not included in the analysis of causes of death.
