Table 4.

Lifetime, 12-month and 7-day prevalence in terms of body regions for all respondents, separated by gender. An asterisk after the chi2 value symbolizes the significance level (* p < 0.05, ** p < 0.01, *** p < 0.001). An ‘a’ stands behind the chi2 test, if Fisher’s exact test was applied when 20% of the cells of a contingency table were below 5.
