Notes: Values are presented as mean ± SD. As LSS-positive in 2004 changed to negative in 2005, of the eight components, only GH improved in a statistically significant manner. Contrarily, as LSS developed from negative in 2004 to positive in 2005, six of the eight components (PF, RP, BP, VT, SF, and RE) worsened in a statistically significant manner.
