Table.

The association between patients' causal attribution (physical or psychological) of the reason for consultation and the detection of common mental disorders by primary care doctors. Only cases diagnosed according to psychiatric interview are included

^*Number of subjects included in the calculation of crude odds ratios. 

^†Logistic regression involved 291 subjects only, because cases with missing data are automatically omitted from the procedure. Using Huber White Robust Estimator for clustering of doctors and adjusted for all study variables. 

^‡Fifteen cases are missing and 55 cases are not included because reasons for consultation were unclear or patients were consulting primarily for administrative reasons (for example, physical check ups, to obtain a sickness note, and so on).
