Results of logistic regression comparing whether foals had resolution of ultrasonographic pulmonary lesions within 28 days with either standard treatment (clarithromycin + rifampin) or GaM, excluding results of one farm (Farm 2) that failed to reliably follow study protocol: effects of treatment group and lesion size. There was no significant interaction between treatment group and lesion size
