To assess the predictive accuracy of the rule, we constructed a 2×2 table for calculation of the following: sensitivity, specificity and positive (PPV) and negative predictive values (NPV).
In some instances this was explained by calculation errors and in others this was because we found there was insufficient information in the primary study to construct 2×2 contingency tables for calculation of diagnostic performance.
ANOVA table consists of calculations that provide information about levels of variability within a regression model and form a basis for tests of significance.

The calculation time breakdown is tabulated in Table 3. Table 3 Break down of calculation time.
The results are given in Table 2. Table 2 Break down of calculation time.
Pairwise matching of the Multifactorial Risk Factor Model data classifications was used to produce two-by-two tables for illustration of calculation methods according to standard epidemiologic procedures [ 19- 22].
