Genes for which the median expression in nonsmokers was > 0.125 RPKM were scored as expressed.
To evaluate if lncRNAs were expressed at high levels in subpopulations of cells, the authors used the lncRNA:mRNA median ratio which compares the median expression of lncRNAs to the median expression of mRNA.
The median expression level and the total expression level are shown as a line and whisker, respectively.
For the organ and tissue transcriptome data, the median expression value within each data set was subtracted for each probe.
Median expression: we found that the relationships with median expression were not linear (Figure 4).
Median expression values for each tag were calculated.
Median expression values were used for redundant probe sets.
Peptide ratios were normalized to the median expression in each time point of the experimental group.
The median expression in GF and CV groups were not significantly different (Fig. 1).
For Kaplan-Meier analysis, the median expression of SOX2 was determined across squamous cell tumors.
Briefly, gene expression values are median centered, setting each gene's median expression value to zero.
