Table 5 Independent predictors for fatal and non‐fatal ischaemic stroke (excluding transient ischaemic attack and haemorrhagic stroke) over a period of 30 years of follow‐up divided into different follow‐up periods.

BMI, body mass index; 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).
