Table 1 The number of judo therapy (J.T.) facilities, their distribution per 100,000 people, and Gini indices in all areas, urban areas, and towns/villages in 2004, 2006, and 2008.

From: Increased number of Judo therapy facilities in Japan and changes in their geographical distribution

  1. Mean values ± standard deviations (95% confidence intervals, C.I.s) of J.T. facilities per 100,000 people are presented; the mean Gini indices (95% C.I.s) of their distributions were estimated using the bootstrap method.
  2. The differences in values were significant (p < 0.05, two-tailed t-test) when compared to those in the previous 2 years.
