Figure 3. Adjusted* least-squares mean telomere length z-scores, by phobic anxiety level, stratified by paternal age (<40 or ≥40 years).

*, Models were adjusted for age in years (continuous), pack-years of smoking (0, >0 to <20, 20 to <40, ≥40), body mass index (continuous, kg/m²) and physical activity (continuous, MET-hrs/wk). Least squares means and 95% confidence intervals are shown. N = 281 excluded due to missing paternal age. ^‡, P-value for test of difference in least-squares means.
