Table 2 One-way ANOVA (Kruskal-Wallis rank test) results for median values of linear dimensional accuracy observed in various bite registration materials at 1-h period.

| BRM – bite registration material; n, number of specimens; IQR – interquartile range; H – difference between 2 or more groups of an independent variable on a continous dependent variable; MRS – mean rank score. Interpretation of groups: CAD, computer aided diagnosis (scannable BRM); Cl, clear BRM (transparent material that shows voids and defects). Statistical interpretation: Test used: one-way ANOVA on ranks (Kruskal-Wallis H test); level of the degree of significance was determined on the value of * significant. | ||||||||||
