  • Serum Available
  • Serum Available from Same Study Year as MGUS Sample

Matching Factors:

  • Gender
  • Race (W/B/O)
  • Study Year of Draw
  • Age at Draw
  • Date of Draw

Match Ratio: 3:1

Match Technique: Individual matching only non-cases as controls.

Additional Matching Comments: Draw age +/- 2 years and draw date +/- 90 days were considered optimal. These were progressively loosened to attain matches. 8 case sets are incomplete due to age/date of draw proximity being inadequate.


Analytes:

  • Adiponectin
  • High-Molecular Weight Adiponectin

Number of Cases: 79

Number of Controls: 229




Site: Lymphoid

Inclusion Criteria:
