Clinical response (CR) was based primarily on global assessment of clinical presentation of participant made by investigator at evaluation time point. At TOC (7 to 14 days after end of treatment \[EOT\]) CR was evaluated as "cure"=resolution of clinical signs and symptoms related to the acute infection, or clinical improvement in which no additional antibiotics were deemed necessary when compared to baseline; "failure"=persistence or progression of baseline signs and symptoms of pneumonia (for example: body temperature, white blood cell \[WBC\] count, respiratory rate, auscultatory findings, cough, sputum production), development of new pulmonary or extrapulmonary clinical findings consistent with active infection and those participants that were not assessed for clinical response due to early discontinuation; "indeterminate"=extenuating circumstances precluded classification to 1 of the above.
