indicates age and sex adjusted proportion (95%CI) of confounder by quintile of CRP.

¥

indicates sex adjusted proportion (95%CI) of confounder by quintile of CRP.

#

indicates age adjusted proportion (95%CI) of confounder by quintile of CRP.

Smoking and drinking are binary variables and are coded as: smoking ever/never smoked, drinking >36g/wk.

High/Low education and income are represented by upper and lower groups of the tripartite variables education = 0-9yrs, 10-12yrs, >13yrs and income = <400 000Kr, 400 000-600 000Kr, >600 000Kr.
