Voice outcomes following total laryngectomy 61 Appendix I Correlations between the outcome measurement instruments for all time points (T0-T3) show statistically significant correlations between AVQI and VHI-10 ( p <.001), Perc. Voice SLP and VHI-10 ( p <.001), Perc. Voice pt and VHI-10 ( p <.001), Perc. Voice pt and AVQI ( p <.001), Perc. Voice pt and Perc. Voice SLP ( p <.001), Perc. Voice SLP and AVQI ( p <.001) and between VHI-10 and EQ-5D-5L ( p =.003). No statistically significant correlation is found between AVQI and EQ-5D-5L ( p =.228). Figure 3.4: Correlation between outcome parameters for all time points.Numbers indicate T (T0-T3). Y ∼ X + (1|Subject) R^2: pseudo R2 (explained variance fixed factors); p: > Chi square (ANOVA vs Y ∼ 1 + (1|Subject)). Abbreviations: 0= pre- laryngectomy; 1= 3 months post-laryngectomy; 2= 6 months post-laryngectomy; 3= 12 months post-laryngectomy.
