These divergent results are likely due to varying methodological conditions, for example, tissue model, cell type, time of treatment, and dose of the extract.
The terms quality, validity, and bias 4 have been used interchangeably in the systematic review literature to describe methodological conditions that are associated with the validity of study results.
Here, we present a review of (i) the advantages and limitations of the use of field plots to measure soil erosion; and (ii) the potential sources of variation in the results obtained due to a lack of harmony between methodological conditions and the processes operating in the environment at different scales.
Moderator analyses confirm that these weak effects are generally consistent (and often non-significant) across a variety of methodological conditions (e.g., different outcome measures, different kinds of samples).
This paper addresses the methodological conditions –particularly experimental design and statistical inference– ensuring the identifiability of sorption parameters from breakthrough curves measured during stirred flow-through reactor experiments also known as continuous flow stirred-tank reactor (CSTR) experiments.
By contrast, in a previous study [17], performed under identical methodological conditions, we found that the frequency of FOXP3 positive T cells in normal skin and a panel of inflammatory skin diseases was in the range of 25 30%, which is significantly higher compared to the situation in atherosclerotic intima and adventitia.
Despite these interesting findings, variations in methodological conditions (microarray platforms, heterogeneous cellular populations, etc).
Most importantly, all major topics were discussed in all FGDs and the methodological conditions above did not, in our view, jeopardise the present analysis.
Two hospital sites with palliative care beds within the Northwest Wales NHS Trust will be randomly allocated one of two methodological conditions, cluster randomisation or Zelen.
All sections from both non-Tg and 3xTg-AD groups at different ages were processed at the same time using precisely the same experimental conditions to minimize methodological variability.
