  • For comparison between baseline and follow-up Wilcoxon signed-rank tests were used and significance set at *=p<0.05, **=p<0.01 and ***=p<0.001.

  • † For comparison between the four alternatives rs=Spearmen´s rank correlation test were used for continuous variables.

  • B, baseline; FU, follow-up.
