  1. Cox proportional hazards regression (n = 801) showing unadjusted ORs (A) and best-fit model including visceral adipose fat (VAT) area and age (B). For evidence of the presented best-fit model and an analysis of residuals to account for co-linearity between adiposity variables, see Additional file 1: Tables S6 and S7, respectively. The study sample prevalence estimate (females > = 40 years) for sub-clinical atherosclerosis at follow-up was 0.27 (average time from baseline to follow up was 9.95 years, range 5–16 years). Explanatory variables VAT, DXA and BMI are all standardised, implying a change in hazard ratio per unit SD change. For Cox proportional hazards, the Wald model-fit statistic is presented to indicate the best model fit (StatCorp, Texas) that predicts onset of sub-clinical atherosclerosis (carotid intima-media thickness, cIMT). Abbreviation: CI - confidence interval.
