Moxifloxacin versus ethambutol in initial tuberculosis treatment.

摘要

Kwok Chiu Chang and Chi Chili Leung question the lack of an association between the number of acid-fast bacilli (AFB) per high-power field (HPF) on sputum microscopy and the presence of cavitation on chest radiograph, and wonder whether differences in smear results at baseline might explain the better outcome with moxifloxacin. The lack of correlation between sputum smear and cavitation also surprised us, and we noted in our Discussion that both variables are semi-quantitativeassessmentssubject to interobserver (and intraobserver) variability
