In order to adjust for any potential differences in biomarker levels obtained at different sites, a dichotomous, nominal variable site (indicating the site where the data was obtained for each observation) was incorporated into the modeling as a covariate.
Since the nominal expression site of OR genes, namely olfactory epithelium, is practically not represented in transcript databases, most of the expression evidence presented here originates from ectopic tissues.
But since the differences were nominal (both sites, for instance, were trumpeting Barbie merchandise), the big news as far as shoppers were concerned was not the return of eToys but rather that the KB Toys people had managed to incorporate eToys.com's best features into the design of the KBtoys.com site.
There were 484 nominal polymorphic sites, and in this first pass analysis, all SNPs were calculated for association, without regard to haplogroup specificity or minor allele frequency.
Of the 345,235 CpG sites, significant sex differences in DNA methylation were observed at 292 CpG sites (nominal p < 1.44 × 10−7, Additional file 1).
However, analysis of sample areas using pixels as individual observations within a statistical distribution indicated that subtle variation and gradients within management or land units could be used to characterize fine differences in selected nominal states at each site.
Similarly, the ratios did not reveal any novel patterns in marker expression when analysed by group or individual for either biopsy site or nominal biopsy time effects, compared to the total- or phospho-marker levels alone (data not shown).
However, for TG and LDL-C, several haplotype windows (some of which harboring only uncommon/rare variants) yielded significant associations despite the absence of (TG) or only few (LDL) nominal associations in single-site analyses.
The secondary objectives of Study B were to assess the intersubject variability, the evidence for any effect of biopsy site or of nominal or actual biopsy time on these marker levels; and to assess the relationship between total and phospho-pRb, and between total and phospho-p27, as ratios.
The company has a freemium business model, whereby users can create mobile sites for free, but can upgrade to more full-featured sites for a nominal fee.
