3.4 Correlation between EGM-thresholds and morphology and vascularization of fPap.
We have used the Spearman-test to calculate any correlation between the EGM-thresholds and the morphology and vascularization of fPap. The null hypothesis was that there is no correlation between the above parameters for all measurements of the study.
On the 1st measurement we have found a correlation coefficient (r) between the EGM-thresholds and the morphology, equal to 0.31. This correlation was significantly increased at the second exam (r = 0.5). Our findings indicate, that the functional improvement of taste acuity does not correlate directly to the morphology (including the vascularization) of fPap. Concerning the vascularization and the EGM-Thresholds, we have found a correlation coefficient (r) on the first measurement equal to 0. 56. This correlation was found increased by the second measurement (r=0.74) This indicates that the vascularization of fPap is not directly correlated to the morphology of the fPap.
