Reply to the Letter to the Editor of J. Padulo et al. concerning 'Calculation of corrected body height in idiopathic scoliosis:-comparison of four methods' by M, Tyrakowski et al. (Eur Spine J, ^i>10.1007/s00586-014-3275-l)

摘要

We are glad that the authors of the Letter to the Editor found the topic of calculating the true body height in patients with scoliosis to be interesting and requiring research. With this response we thank the authors of the letter for pointing methodological inconsistencies of our study [1].; We agree that other statistical methods should have been used [2-6], so we repeated the analysis using the intraclass correlation coefficient (ICC) and the median error for a single measurement (SEM), and obtained substantially similar results. There was an insufficient overall agreement between all the methods tested with the ICC of 0.66 and SEM of 5 mm. Comparison of pairs of the methods is presented in Table 1.
