Task: Answer Verification
Input (English): Question: Is methacholine responsiveness associated with O3-induced decreases in FEV1?
Answer: Although we were unable to find support for our hypothesis, we found, somewhat surprisingly, that respiratory symptoms were weakly associated or unassociated with FEV1 responses after O3 exposure. This finding implies that individuals may experience adverse effects, ie, respiratory symptoms, without large declines in lung function. Conversely, individuals may suffer large declines in lung function without prominent symptoms and, therefore, may remain in an unhealthy environment despite evidence of toxicity.
Output (English): no
