FIGURE 2.

Flow chart describing classification of patients for physical examination and intervention, based on outcome of process described in Figure 1. Red flag physical test results (Table 6) can be identified in any group of patients; patients with red flags are automatically classified High Irritability. Irritability may increase during or up to 24 h after the physical exam (dotted arrow labeled “Flare”), shifting patients to a higher irritability group. See text and tables for more detailed discussion of each step in the process.
