Survey-specific proportions or means (95% CI) are age-adjusted post-estimated marginal means from GEE models, holding age constant at the sex-specific mean in both surveys together (57.49 years for women, 58.15 years for men). The GEE logistic or linear regression models were stratified by ethnicity and run with age and survey as covariates.
*P values for the survey, that is, p value for change in proportion or mean from SAMINOR 1 to SAMINOR 2.
†Geometric means due to the log-transformed outcome.
ATP-III, Adult Treatment Panel III; GEE, generalised estimating equation; HDL, high-density lipoprotein; MetS, metabolic syndrome.
