The factor matrix for principal component analysis.
| Principal Components | ||
|---|---|---|
| Item | 1 | 2 |
| Neutrophils | 0.955 | −0.189 |
| Eosinophils | 0.953 | −0.237 |
| Mucus | 0.935 | −0.057 |
| Lymphocytes | 0.906 | 0.127 |
| IgE serum | 0.437 | 0.764 |
| IgG2a BALF | 0.294 | 0.594 |
| IgG2a serum | 0.113 | 0.622 |
| Collagen | −0.053 | 0.787 |
| Macrophages | −0.908 | 0.212 |
Note: The column values representing the factor loadings (correlation coefficients) show that neutrophils, eosinophils, mucus and lymphocytes were strongly, positively correlated with PC1 and macrophages were negatively correlated with PC1. PC2 variance showed a strong positive correlation with IgE serum, collagen, IgG2a serum and IgG2a BALF.
