However, comparison of data from different studies shall be taken with caution since there are substantial methodological variations that may have influenced on the overall HPV positivity, as paraffin-embedded versus fresh-frozen tumors, and on the individual rate of HPV types, obviously driven by the inclusion of type-specific detection probes on the post-PCR hybridization steps.
There is, however, no general agreement among investigators on how to express data and to define, considering methodological variations, depressed or activated T-cell responses [ 13- 17].
This difference could be due to methodological variations; in the case of the Jimma study, the result was confirmed based on the test result of HIV and STIs, where as in the present case, it was merely self report.
It is likely that the differences are partly due to the methodological variations in assessing strength, but it also possible that testosterone has different effects on the various muscle groups.
However, it is important to note that the estimated coalescence ages are approximate, as a few methodological variations may lead to somewhat different results.
With the release of substantial information on a range of AEDs (both older and newer generation drugs), it becomes increasingly important to understand how the methodological variations between cohorts may affect the risks of major birth defects being reported.
For the analysis of specific gene families, methodological variations were introduced as reported in text.
This high discrepancy is mainly due to the methodological variations.
There were methodological variations across TCM interventions (table 3).
We stored plasma at −80°C to allow uniform BNP measurements on one occasion with minimal methodological variation.
