  1. Data are presented as the means (SD) and n (%); y = yes * P<0.001 vs. each other region; *** p<0.002 vs. each other region; **** p<0.01 vs. each other region; ### p<0.005 vs. each other region; + p<0.01 vs. north/northeast and mid–west regions For comparison between continuous variables ANOVA with Sidak correction were used; For comparison between discrete variables two-sided z-tests with correction was used.
