Figure 1. Crude Mean Health-Status Scores in the Overall Trial Population.

Figure 1.

Observed mean health-status scores from randomization through 48 months are shown. Shading represents the 95% confidence interval. On the Seattle Angina Questionnaire (SAQ), the SAQ Summary score is obtained by averaging the SAQ Angina Frequency, SAQ Quality of Life, and SAQ Physical Limitation scores; SAQ scores range from 0 to 100, with higher scores indicating better health status. On the Rose Dyspnea Scale, scores range from 0 to 4, with higher scores indicating dyspnea with milder activities. On the European Quality of Life–5 Dimensions (EQ-5D) visual analogue scale, scores range from 0 to 100, with higher scores indicating better health status.
