Rotated factor loadings for patient-centred measures
| Variable | Patient Factor 1 |
| Quality-of-life score (reversed) | 0.842¶ |
| Asthma control questionnaire (reversed) | 0.870¶ |
| Median daily control score | 0.753¶ |
| Patient global control assessment | 0.855¶ |
Table shows the rotated factor loading between each individual variable and the factors derived from principal component analysis for patient-centred variables. ¶: Significant loadings, indicating the variables that clustered together, i.e. were strongly correlated with each other.
