(A,B) Distribution of asthma with increasing systolic and diastolic blood pressure by sex. With increasing systolic blood pressure, prevalence of ‘ever’asthma tended to decrease in men (p for trend = 0.04) and increase in women (p for trend < 0.01). Similarly, with increasing diastolic blood pressure, prevalence of ‘ever’asthma tended to decrease in men (p for trend < 0.01) and increase in women (p for trend < 0.01).
