Figure 2 Comparison of SSS and SDS for Initial Adenosine and Randomized Scan
Using the rounded average of 3 readers for adenosine-adenosine and adenosine-regadenoson scoring, mean summed stress score (SSS) (A) and summed difference score (SDS) (B) differences were close to 0 and standard deviations (SDs) were similar for the 2 arms for the ADVANCE MPI 1 and 2 trials. The differences between the initial adenosine and randomization to regadenoson were no different than randomization to repeat adenosine. Results of ADVANCE MPI 1 are shown.
