Table 2 Changes from baseline to 9 months in primary outcomes, bone mineral density (BMD) and bone turnover markers.

From: Impact of Tai Chi exercise on multiple fracture-related risk factors in post-menopausal osteopenic women: a pilot pragmatic, randomized trial

  1. * p-value for comparison with Usual Care based on the Wilcoxon rank sum test.
  2. Baseline and 9 month values represent mean values ± standard deviations. Change scores are summarized with median values and 25th (Q1) and 75th (Q3) percentiles. P-values indicate comparisons between Usual Care ground and Tai Chi and Per Protocol groups, based on the Wilcoxon rank sum test.
