Fig. 2From: Non-linear associations between healthy Nordic foods and all-cause mortality in the NOWAC study: a prospective studyIntake of Nordic fruits and vegetables and all-cause mortality by restricted cubic splines stratified by never and ever smokers. From: Non-linear associations between healthy Nordic foods and all-cause mortality in the NOWAC study: a prospective study. Nordic fruits and vegetables modeled by restricted cubic splines with 3 knots at percentiles 10%, 50% and 90% (Never smokers: 65; 173; 343. Ever smokers: 53; 160; 332). Black line hazard ratio, grey area 95% confidence interval. Age-adjusted and mutually adjusted for the healthy Nordic food groups, BMI < 20, 20–24.9, 25–29.9, ≥ 30 (kg/m2), physical activity (low, medium, high), education (< 10, 10–12, > 12 years of schooling), intake of energy (kJ/day continuous), alcohol (non-consumer, 0–5, > 5 g/day), and processed red meat (< 15, 15–29, 30–44, ≥ 45 g/day). *Additionally, adjusted for pack-yearsBack to article page
