TROMSO_STR3

Name: STR3

Description and values:

• 1 = yes, fatal
• 2 = yes, non-fatal
• 3 = no event during follow-up

Local variable explanation:

DIAGHEMO: Diagnose of haemorrhagic stroke (1=definite)

DATOHEMO: Date of diagnose of haemorrhagic stroke

FLYTTEDATO: Date of relocation from town/municipality

DATE_T4: Date of examination

DATO_DOD: Date of death

fdato: date of death

SAS code:
If DIAGHEMO = 1 and (sign(DATOHEMO -'31dec2010'd)=1 or sign(DATE_T4 - DATOHEMO)=1) then do;

DIAGHEMO=.;

DATOHEMO=.;

end;

IF DIAGHEMO = 1 and sign(DATOHEMO-FLYTTEDATO)=1 then do;

STR3=3;

end;

ELSE IF DIAGHEMO = 1 and .<(DATO_DOD -DATOHEMO)<=28 then do;

STR3=1;

end;

else if DIAGHEMO = 1 then do;

STR3=2;

end;

else do;

STR3=3;

end;

if bbb ne 1 then STR3=3;
if str_hist1=1 and several_strokes=0 then str3=3;
if str3=. and several_strokes=0 then str3=3;

if (TYPE1='430' OR TYPE1='431') AND (contact_age<age_strokediagn) and survival=1 then STR3=2;
if bbb ne 1 then STR3=3;

TYPE1=type of stroke according to the ICD codes.
age_strokediagn is the age at stroke diagnosis.
survival=survival at day 28, 1=yes, 2=no.
bbb=1 means that the person exists in the stroke registry.
several_strokes: 1=person has had several strokes, 0=person has not had several strokes.

MORGAM_STR3

This was derived from the MORGAM derived variable STROKE5 using the following rule:

Note, when STROKE5 = 8 or 9, STR3_TIME will be zero.
