Table 4 Independent predictors for fatal and non‐fatal any‐cause stroke (including transient ischaemic attack and haemorrhagic stroke) over a period of 30 years of follow‐up divided into different follow‐up periods.

Follow‐up period	0–30 (age period 50–80 years)		0–9.9 (age period 50–60 years)		10–19.9 (age period 60–70 years)		20–30 (age period 70–80 years)
Characteristics	HR (95% CI)	p Value	HR (95% CI)	p Value	HR (95% CI)	p Value	HR (95% CI)	p Value
SBP supine	1.38 (1.26 to 1.51)	<0.001	1.50 (1.19 to 1.89)	0.001	1.47 (1.27 to 1.70)	<0.001	1.21 (1.05 to 1.40)	0.008

SBP, systolic blood pressure.

HRs with 95% CIs from Cox's proportional hazards regression were applied to variables standardised to 1 SD. Stepwise multiple regression analysis were performed for each decade of follow‐up and only variables retained in the models are presented (p<0.05).
