  1. The 6 different preparation and storage (P + S) conditions are as followed: P + S 1: centrifuge + storage at -20°C; P + S 2: centrifuge + storage at -70°C to -80°C; P + S 3: analyzed immediately after sampling without centrifuging or storing; P + S 4: storing at 4°C without centrifuging; P + S 5: storing at 37°C without centrifuging; P + S 6: immediately centrifuged after sampling and analyzed without storing
  2. Note: "≈" indicates no significant difference, ">>" indicates significant difference between the outcomes
