175 Oral dryness and use of dry-mouth interventions Table 7: The odds ratio of several independent variables (RODI-scores, total XI-scores, BI-score) for the significant interventions after univariate analysis. The odds ratio including the 95% CI is reported. For the significant associations also the last step of the Omnibus and H-L test Chi-square including their df and p-values were reported. Furthermore, the Coxx & Snell and the Nagelkerke R square were mentioned.
