Ambient Temperature and Outpatient Visits for Acute Exacerbation of Chronic Bronchitis in Shanghai: A Time Series Analysis

摘要

The association between ambient temperature and acute exacerbation of chronic bronchitis(AECB)was still unknown.Therefore,we performed an epidemiological study in a large hospital of Shanghai to explore the relationship about temperature and outpatient visit for AECB.We adopted a quasi-Poisson generalized additive models and distributed lag nonlinear models to estimate the accumulative effects of
