1 For BG the sample sizes are: N = 79, N = 408, N = 210, and N = 30 respectively for the BMI categories; N = 527 and N = 200 for the WC categories; N = 508 and N = 219 for the WHpR categories; N = 532 and N = 195 for the WHtR categories. 2 Standard error of the mean. 3 F-statistic from ANCOVA including age, sex, tobacco use, and the year of examination as covariates. 4 Not significant. 5 Male-specific cut-off value. 6 Female-specific cut-off value. 7 F-statistic from ANCOVA including age, tobacco use, and the year of examination as coviariates.
