Figure 3 Changes in the Severity of Angina Symptoms During the Follow-Up
Note that the severity was significantly lower in the PCI plus medical therapy group than in the initial medical therapy only group. *p < 0.05. **p < 0.01 vs. the PCI plus medical therapy group. #Overall, the interaction between treatment and time was tested in repeated-measurement multivariate analysis of variance for complete cases. After missing observations were imputed using the last observation carried forward method, the p value was <0.0001. Abbreviations as in Figure 1.
