Intake of Nordic food groups and all-cause mortality by restricted cubic spline regression. From: Non-linear associations between healthy Nordic foods and all-cause mortality in the NOWAC study: a prospective study. Nordic food groups modeled by restricted cubic splines with 3 knots at percentiles 10%, 50% and 90% (Nordic fruits and vegetables 57; 164; 336. Low-fat dairy products 0; 138; 550. Fatty fish 0; 13; 35. Lean fish 0; 24; 66 g/day). Black line hazard ratio, grey area 95% confidence interval. Mutually adjusted for the healthy Nordic food groups, age (underlying timescale), BMI < 20, 20–24.9, 25–29.9, ≥ 30 (kg/m2), physical activity (low, medium, high), smoking status (never, current heavy smoker early starter, current moderate smoker early starter, current smoker late starter, former smoker early starter, former smoker late starter), 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), stratified by subcohorts (n = 5)
