  2. aReferent quartile
  3. bP value for continuous quartile trend in cytokine concentration
  4. cP value for continuous trend in log-transformed cytokine concentration
  5. dAll hazard ratios are adjusted for type of military service and represent change in risk per quartile increase in cytokine concentration
