Relationships between salivary inflammatory marker principal components and measures of asthma control among adults with asthma*.

*regression models include all three PC scores; relationships were modeled using multiple linear or logistic regression; bolded results are statistically significant at padjusted for number of teeth, gingivitis, oral prednisone, inhaled corticosteroids.Principal Component 1 reflects relative similar representation of all markers with slightly greater weight to innate/myeloid markers.Principal Component 2 reflects greater representation of eosinophil/lymphoid markers relative to innate markers.Principal Component 3 predominantly reflects IP-10/CXCL10.ACQ: Asthma Control Questionnaire, ACT: Asthma Control Test.
