Figure 2. Adjusted* least-squares mean telomere length z-scores, by phobic anxiety level, stratified by smoking status (never or current/past).

*, Models were adjusted for age in years (continuous), paternal age-at-birth (15–24, 25–29, 30–34, 35–39, ≥40 years), body mass index (continuous, kg/m²) and physical activity (continuous, MET-hrs/wk). Least squares means and 95% confidence intervals are shown. N = 20 excluded due to missing smoking status. ^‡, P-value for test of difference in least-squares means.
