  1. *LOS with a specific comorbidity is defined as the days above the median LOS in patients without this comorbidity. The median LOS without each specific comorbidity was 11 days for all hospitalization episodes.
  2. #Statistical significance was determined by the Mann–Whitney U test with significance at p < 0.05.
  3. ¥Number of people in each gender per 1,000 inpatients diagnosed with a specific comorbidity.
  4. LOS = length of hospital stay.
