The authors of the TEAR article appreciate the letter from Drs. Graudal and Jürgens, requesting that we provide a table showing the mean ± SD change in the scores for the 4 groups (0–2 years). We addressed this issue in our article in the section on radiographic results, where we noted that a nonparametric analysis (rank progression) was performed, the results of which were in accordance with the points raised by Graudal and Jürgens. We are aware that there are potentially multiple approaches to analyzing these data, including nonparametric analyses, which is why we included this result in the report.
