It is important to mention that some of the factors in our regression models are confounding; for instance, PEPFAR focus countries are mainly low-income countries.
In some instances, confounding variables (such as police discretion in making arrests) are difficult if not impossible to measure.
The meeting had its light moments too -- when Mr. Bush and Mr. Ivanov started conversing in Spanish, for instance, confounding the Russian translator.
Shorter segments likely capture too much variability in the instrument's time profile hence producing inconsistencies in the features learnt from each class, for instance confounding the transient and steady-state nature of the signal.
First, our study design of HCC samples was retrospective and, for instance, confounding of SLC22A1 expression cannot be excluded with certainty.
A further strength is the complete study sample; moreover, several potential confounders were taken into account, even though we cannot rule out the risk of unmeasured or residual confounding, for instance, from other psychosocial factors like catastrophising and somatisation.
The company often irked suppliers and confounded pundits, for instance, when it chose to use 3.5-inch floppy disks instead of the more common 5.25-inch disks, or later, when it did away with floppy disks altogether.
Individual studies have generally been limited by small numbers of adenocarcinoma cases and in some instances by lack of adjustment for confounding factors.
Since this correlation was made between induction/repression ratios, it is corrected for confounding effects, such as gene expression levels for instance.
In instance of considerable variation in data confounding inferences, the data outside of 1 S.D. might have been equilaterally excluded from the data used for statistical analysis.
