Its organ size, body mass, and physiology strongly resemble those of humans (Sachs 1994; Schook et al. 2005), and the immune system of pigs is more similar to that of humans than it is to the immune system of rodents (80% similarity of the compared variables between pigs and humans versus 10% between mice and humans) (Schook et al. 2005).
Moreover, most R between the dependent and independent variables 'gene expression value' and 'treatment time point' were close to 1.0 at adjacent time points (Table 6), which indicated a strong linear relationship between compared variables.
We compared variables between the newly classified and previously classified patients; the results are summarised in Table 3.
Furthermore, when we compared variables between the newly and previously classified patients, although sclerodactyly did not differ significantly between the two groups, telangiectasia and anti-centromere were significantly more frequent in the newly classified patients.
We compared variables between groups using Wilcoxon rank sum tests.
Although we do not advocate testing for differences in baseline variables, our results showed that more trials adjusted for baseline variables when significant differences had been noted between the compared arms in these variables; however, there were many exceptions to this pattern.
The Kruskal-Wallis test for continuous data and chi-square test for categorical data were used to compare variables between the surviving and dead groups and between the favorable and unfavorable neurologic outcome (CPC 1-2 versus 3-4) groups.
In an in-depth follow-up study comparing variables between the Columbia and Minneapolis men, the researcher discovered that the Missouri group had had higher exposure to agricultural pesticides.
t test will be used to compare variables between the groups where the data are approximately normally distributed, possibly after transformation.
