Comparison of gene expression in whole blood lysates and extracted RNA. a-i Genes that are affected by the collection tube or RNA extraction system (see Fig. 5) were measured by NanoString arrays in matching whole blood lysate and RNA samples prepared using the PAXgene or Tempus system (n = 11 per group). j Table showing relative levels of expression between groups. For all genes, expression was most similar between the Tempus whole blood lysate and Tempus RNA samples. The PAXgene lysate samples were also more similar to the Tempus lysate and Tempus RNA samples, than to the PAXgene RNA samples. *P < 0.05, **P < 0.01, ***P < 0.001, two-tailed Wilcoxon matched-pairs signed rank test
