| Extracted molecule |
total RNA |
| Extraction protocol |
Samples were stored at -80⁰C until RNA extraction
From PAXgene tube samples, total RNA was purified from 2.5 mL of whole blood using Rneasy mini kit (Qiagen, Chatsworth, CA, USA)
From EDTA tube samples, total RNA was purified from 3.0 mL of whole blood following modified TRIzol-based extraction method.
The yield and quality of RNA was assessed by NanoDrop 8000 Spectrophotometer (Thermo Scientific, Wilmington, DE, USA) and Agilent 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA, USA)

| Data processing |
Raw data normalization using the 'farms' package consisted of RMA background correction, quantile normalization and summarization of probe-level data using Factor Analysis for Robust Microarray Summarization
Data filtering was also performed using the Informative vs. Non-Informative Calls function in the 'farms' package. Differential gene expression was determined using moderated t-tests in limma using an FDR cut-off of 10%.
All statistical analyses were performed in the statistical computing program R.
