Mann-Whitney U-test of significance (two-sided) was used to measure the distribution of ranks between non- critical and critical cases; z-statistic and p-value of the non-parametric test is noted.
Multiple Linear Regression Model (dependent variable: plasma marker as continuous variable that were subjected to log-transformation and standardizing; independent variable: non-critical vs critical) was used for the models, presented as T-statistic and adjusted for age and gender.

Supplementary Table 4. Unadjusted and Adjusted effect size and p-value of the following genes:
CCR1, CCR2, CCR3, CCR5, CD46, CXCL16, CXCR6, DPP9, FYCO1, IFNAR2, IFNG, IL1, IL6, LIMD1, LRRC2, LZTFL1, OAS1, OAS2, OAS3, SLC6A2, SLC6A20, VSTM2A, XCR1, TNF-A, MIP, CXCL10, CCL7, CCL2, CCR9, CD40, FCGR2, IL17, PEDS1. Two candidate gene association tests were conducted that included unadjusted analysis (correction for population stratification using the top ten eigenvectors) and adjustment analysis (correction for population stratification using the top ten eigenvectors, age, and gender). Association was measured using logistic regression, assuming additive allelic effects.
