Figure 2. Predicted relationship of probability of somatic intervention as outcome of consultation to duration of consultation (seconds) and to the number of instances of specific speech categories by patients (symptom and psychosocial presentation) and general practitioners (GPs) (normalization and psychosocial explanation). Relationships control for other variables in the regression analysis that included patients’ and GPs’ speech. Lines show values predicted by the cumulative effects of the coefficients shown in Table 3.
