Moreover, in the few instances that informal care is included in economic evaluations, the comparability of results is hampered by differences in measuring and valuing informal care [ 18- 20].
The differences in behavioral seizure intensity were paralleled by differences in electrophysiological measures of seizure duration.
Comparison of our results with previous studies is limited by differences in outcomes measured and populations studied.
The introduction of population movement into an area characterized by sustained differences in measures of population health allows for the transfer or elaboration of these characteristics between locations.
The differences in the results of the two studies are most probably caused by differences in the fitness measures; in the previous study, we counted the number of eclosed offspring per population, whereas in the current study we used measures of individual fitness.
The effect of community-level intervention, measured by difference-in-difference method, was 66.5% (Table 1).
In contrast to studies of other proteins, the extent of IB formation is not explained by differences in thermal stability measured by differential scanning calorimetry.
Thus, it is clear that differences in visceral fat and the abdominal subcutaneous fat distribution may not be reflected by differences in its surrogate measure, that is, WC [ 33, 34].
However, trend analyses of national asthma prevalence and international comparison of asthma prevalence in different populations have been constrained by differences in definitions and inconsistent measures of asthma used in prevalence surveys [ 5].
In addition, to assess the extent to which these fitness measures may be biased by differences in offspring characteristics, we measured size at birth and growth rates, which have been previously described as important fitness correlates.
