85 5 significant correlations were found for the item total SWAL-QOL score (Spearman’s ρ=0.398, p<0.001). As example, Figure 2b displays the total score on the SWAL-QOL questionnaire versus the number of swallows of the WST, and Figure 2c displays the total score on the SWAL-QOL questionnaire versus the duration of the WST, both at M6. Correlations between the WST and all items of the EORTC-QLQ-H&N35, SWAL-QOL, and GRIX are shown in Appendix 4, 5, and 6, respectively. Table 2.
