Data are presented as hazard ratio (95% confidence interval), comparing F/CRP ratio quintiles 1 and 2 with quintiles 3, 4 and 5 (reference), adjusted for age, sex and forced expiratory volume in one second (% predicted). CHD: coronary heart disease; CVD: cardiovascular disease. #: n = 4,809; ¶: n = 853; +: n = 1,360; §: n = 2,596.
