Note that age and year are in this table determined exceptionally by date of death
Total fatal registration: Total number of fatal events
Fatal events with STR: Number of events with 430-434 or 436 in one of the three clinical or death certificate diagnosis
Routine STR mortality: Number of deaths in the routine statistics (FORM C or E) with ICD code 430-438
Register/routine ratio, STR/STR: Fatal events with STR/Routine STR mortality (in the text referred as STRRATIO)
Register/routine ratio, Total/STR: Total fatal registration/Routine STR mortality (in the text referred as TOTRATIO)
