In particular we observed that DWD, a popular method used in a number of previous studies, removed systematic bias at the expense of genuine biological variability, potentially reducing legitimate biological differences from integrated datasets.
The mRNA regression results are similar to those of previous studies [ 20, 21], which used microarrays or RNA-Seq, but an important difference is that we, in contrast to previous studies, removed transcriptionally silent genes before the analysis.
Previous studies have removed female professional sex workers (or those assumed to be) from their analysis (Breslow et al., 1985; Levitt et al., 1994).
Different DIF relations including CEB defined DIF, DIF proposed in previous studies after removing structural effect in laboratory tests, and NO DIF, i.e., neglecting dynamic strength increment, are considered in numerical simulations.
Linear mixed-model frameworks have been successfully used in previous studies to remove confounding effects when performing eQTL analysis (Kang et al., 2008).
In our previous study, we removed redundant copies of mRNA before mapping [ 32], whereas in this study, we removed not only redundant mRNA sequences but also redundant copies of poly(A) sites from duplicated or repetitive genes to ensure that each poly(A) site was unique, because of lack of evidence about whether every copy of multiple-copy genes was actually expressed.
In a previous study, we removed differing amounts of the antenna, to determine how many ORN axons are necessary for normal development of the glomerular array in the AL.
Among the 60 subjects analyzed in the previous study, we removed data of nine subjects in the present study because their DWI data were not obtained in the same sequence as other subjects.
The analysis method differed between this study and our previous study [ 32] in that this study removed all the redundant poly(A) sites (keeping only one copy per group), whereas the previous study [ 32] kept all poly(A) site copies on the reference genome, although both studies removed the redundant copies of mRNA before the mapping was conducted.
In a previous study, to remove methyl blue from aqueous solutions, highly ordered nickel-supplemented MCM-41 adsorbents were synthesized (with varying nickel contents) [14].
Furthermore, the change of culture medium in previous studies might also remove proliferating myocytes and emerging MDCs that are semi-adherent and exhibit progenitor cell phenotypes.
