Association of Chronic Cough and Pulmonary Function with 6-Minute Walk Test Performance in HIV Infection. Chronic lung disease has been associated with greater impairment in self-reported physical function in HIV patients. We sought to study this association using objective measures of physical or pulmonary function. We assessed the association between clinical, laboratory, and pulmonary function measures on six-minute walk test (6-MWT). Multivariable linear regression models were generated to identify factors associated with 6-MWT performance.
