Cytokines that significantly differed between animals with or without VAP, per times of assessment. a IL-10 differed among animals with or without VAP (p = 0.028) and for occurrence of VAP × study treatments (p = 0.029); whereas, among times of assessment (p = 0.984) and occurrence of VAP × times of assessment (p = 0.999) no differences were found. b TNF-α differed among types of pulmonary infection (p = 0.003) and study treatments (p = 0.008); whereas, among types of pulmonary infection × study treatments (p = 0.007); times of assessment (p = 0.984) and types of pulmonary infection × times of assessment (p = 0.995) no differences were found.
