  1. aUsing only the official SINAN period (2000-2012) assuming zero notification incidence for all years and ages from 2000 backwards until 1932
  2. b Calculated from real data (2000-2012) and extending the data backwards assuming a sigmoidal decay until 1932
  3. c Taking the average number of cases reported annually to SINAN between 2004 and 2012, a period in which a steady state could be assumed
