  1. ENRICA, Study on Nutrition and Cardiovascular Risk Factors in Spain; ELSA: English Longitudinal Study of Ageing
  2. T: Tertile (T1, T2 and T3: Tertiles 1, 2 and 3); M: Men; W: Women. OR: Odds ratio; CI: Confidence interval
  3. Beta coefficients and their 95% confidence intervals were obtained from multiple lineal regression models. Odds ratios and their 95% confidence intervals were obtained from multiple logistic regression models
  4. Models were adjusted for age, sex, educational level, body mass index (<25, 25-29.9, ≥30 kg/m2), tobacco (never-, ex-, current-smoker), total energy intake (kcal/day), MEDAS index, physical activity, cancer, diabetes, cardiovascular disease, osteomuscular disease and chronic respiratory disease. All linear regression models were also adjusted for the baseline PCS score. Note that in the ELSA study no adjustment was made for the MEDAS indexor for energy intake
  5. Results from the two cohorts have been pooled using random-effects meta-analysis
