Figure 4: Predicted probability of hypotension associated with overall sound exposure (road and rail traffic, Leq 24 h) by age and symptoms of exhaustion. Adjusted for family history of hypertension, education, community, weather and noise sensitivity, sleep problems, symptoms of fatigue and depression. Including interaction terms age × sex, age × weather sensitivity, noise sensitivity × weather sensitivity, Leq 24×exhaustion, Leq 24×sleep problems Grey shaded areas represent 95% confidence limits
