Fig.1 Initial and final %FFA values for the exposed and
unexposed TOs. Final values indicate the values obtained on the
7th week. Values are reported as mean±SD at 95%
confidence interval (N=4)
Fig.2 Initial and final peroxide values for the exposed and
unexposed TOs. Final values indicate the values obtained on the
7th week. Values are reported as mean±SD at 95%
confidence interval (N=4)
Fig.3 Initial and final iodine value values for the exposed and
unexposed TOs. Final values indicate the values obtained on the
7th week. Values are reported as mean±SD at 95%
confidence interval (N=4)
Fig.4 Initial and final colour content for the exposed and
unexposed TOs. Final values indicate the values obtained on the
7th week. Values are reported as mean±SD at 95%
confidence interval (N=4)
