The results showed that 16 cases out of 20 [80%] had latent asthma. The positive cases showed reducibility of FEVI [forced expiratory volume in the first second] by 20% and PD20 [provocation dose causing 20% decrease in FEVI was calculated. There was a statistically significant increase as regards pulse and systolic blood pressure in the positive cases.
