Table 1.

Out of the 317 patients reviewed, 42 met criteria for Retx analysis. The left side of the table shows the demographic data for the patients for the Retx #1 series unless otherwise specified, where appropriate data is presented as mean ± standard deviation and the minimum value to maximum value in parenthesis. Of note, no significant difference was present between Index and Retx for the total # treatments (p = 0.201). The right side of the table shows the response/remission rate for each series, including those who came back for more than 1 retreatment. Due to the limited sample sizes, no further analyses for Retx #2–5 were performed.
