A Placebo-Controlled Trial of Percutaneous Coronary Intervention for Stable Angina

Figure 1. Primary end point of angina symptom score and its constituents. Panel A shows the individual patient data composition of the primary end point (angina symptom score) stratified by treatment allocation. The method for derivation of the score is depicted below and the overall calculated score is shown next to the colored box. Panel B shows individual patient data of daily angina episodes irrespective of the units of antianginal medication prescribed. Panel C shows the number of units of antianginal medications prescribed for each patient on each day of the trial.

Figure 2. Secondary end points. Panel A shows treadmill exercise at follow-up stratified by baseline performance, with 95% confidence intervals. ETT denotes exercise treadmill time. Panel B shows the distribution of CCS class according to treatment group at pre-randomization and follow-up. CCS denotes Canadian Cardiovascular Society class. The widths of the confidence intervals have not been adjusted for multiplicity. Thus, the confidence intervals should not be used to reject or not reject treatment effects.
