  1. aadjusted for all risk factors displayed in the table
  2. bnota bene: These estimates are dependent on the order of the risk factors, in this case the order in which the variables are reported in the table.
  3. cnota bene: These estimates are dependent on the order of the risk factors, in this case the opposite order in which the variables are reported in the table.
  4. dBruzzi's method allows calculating a summary AF that is not the sum of all individual AF.
