Figure 1. Unadjusted Mean Health-Status Scores Over Time.

Figure 1.

Shown are mean health-status scores among participants who were randomly assigned to undergo initial coronary angiography and revascularization plus receive guideline-based medical therapy (invasive strategy) or to receive guideline-based medical therapy alone (conservative strategy). Shading represents the 95% confidence interval. On the Seattle Angina Questionnaire (SAQ), the Summary score (Panel A) is an average of the Angina Frequency, Quality of Life, and Physical Limitation scores (Panels B, C, and D, respectively); SAQ scores range from 0 to 100, with higher scores indicating better health status. On the Rose Dyspnea Scale (Panel E), scores range from 0 to 4, with higher scores indicating shortness of breath with milder activities. On the European Quality of Life–5 Dimensions (EQ-5D) visual analogue scale (Panel F), scores range from 0 to 100, with higher scores indicating better health status.
