Figure 1. Odds ratios and 95% confidence intervals linking unit increases in each independent variable to the probability that the consultation will lead to somatic intervention, controlling for other variables in the analysis. Separate analyses (upper panel) examine patients and general practitioners (GP) speech; the combined analysis (lower panel) examines both. Duration of consultation was included in all analyses; for clarity, this odds ratio refers to minutes.

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.
