Despite of much effort to study motivations to become a teacher across countries, there is a lack of comparative evidences, caused by the variety of instruments, which differ substantially between the different studies.
The ionisation efficiencies differ substantially between the four different compounds: While MeHgCys exhibits the lowest intensities, with 2 × 10 counts, the MeHgGS signal is tenfold higher.
However, the intervals between data collection, blood sampling, and diagnosis differ substantially between the three different study populations, something that might be considered a limitation of the study.
Although some differences emerged within groups, they did not differ substantially between the groups.
Changes in clinical outcomes after atorvastatin treatment are listed in Table 2 and illustrated in Figure 2. At 4 weeks, the change in mean morning PEF, as compared with baseline, did not differ substantially between the atorvastatin and placebo treatment periods [mean difference -10.67 L/min, 95% CI -38.70 to 17.37, p = 0.449].
At the final study visit (12 weeks) the change in mean morning clinic PEF (primary outcome), as compared with baseline, did not differ substantially between the azithromycin and placebo treatment groups (mean difference -10.3 (95% CI 47.1 26.4 L·min−1), p=0.58) (table 1).
For the majority of the phenotypic traits measured, the coefficient of genetic variation did not differ substantially between the two rhizobium treatments (Table 1), suggesting that the differences in heritability were due to differences in phenotypic variation or environmental effects.
As for risk-taking behavior, tobacco use did not differ substantially between the two groups.
However, the specific contacts differ substantially between the two complexes.
Furthermore, land use and urban planning differ substantially between the U.S. and Europe.
