Also known as weak invariance [ 27], the issue here concerns the degree to which a one-unit change in the underlying factor is associated with a comparable change in measurement units for the same given item in each group.
This study highlights the potential for issues to arise when interpreting water turbidity datasets that are often assumed to be comparable, in that measurement inconsistency of the type reported here may remain unknown to water resource decision-makers and practitioners.
Both methods were comparable in the measurement of gait with the Traditional method demonstrating high level of repeatability.
The modified CMA4 index in particular, which would correspond to Hess et al.'s [ 1] definition of the Medication Possession Ratio, could be much more easily computed than any of the CMG-based measures and it is not unreasonable to hypothesize that it might be fairly comparable in its measurement properties to CMA7 and CMA8.
Hence, the monitoring of ecological effects of GMO must be standardised with regard to parameters, methods, survey intervals and sites so that data are comparable in terms of measurement methods and, thus, can be analysed statistically and interpreted meaningfully [22].
On the other hand, standardized coefficients make unstandardized coefficients comparable in terms of measurement unit based on z scores with a mean of 0 and a standard deviation (SD) of 1 [ 23, 24].
Notably, while median lifetime average hours/week of household and occupational activity were comparable in both questionnaires, measurement of lifetime sports/recreational activity was lower in the L-PAQ than in the LT-PAQ (i.e., 1.5 lifetime average hours/week in the L-PAQ vs. 3.2 lifetime average hours/week in the LT-PAQ).
Information given was coded to provide summary measures of frequency of remembered falls comparable with measurement periods used earlier in the CC75C study and in other studies.
This is usually unfeasible, but if the staff density indeed allows this, our study indicates the MU to be acceptable for hourly UO measurements and comparable to the AU in measurement performance.
In those patients, the clinical role of measuring cTn is controversial and not at all comparable to the measurement in patients presenting with suspected AMI.
The measured IC50 was 1.9 ng ml-1 (8.7 nM), which was comparable to measurements shown in the literature (7 nM) [19].
