Table 3 Statistical comparison of tumor load between different cell populations

From: Molecular purging of multiple myeloma cells by ex-vivo culture and retroviral transduction of mobilized-blood CD34+ cells

  ESTIMATED DECREASE (RATIO) 95% CONFIDENCE INTERVAL P VALUE
CD34 + fresh cells versus CD34 + cells after culture 6.86 1.75 27.17 5.78 × 10-3
CD34 + fresh cells versus ΔNGFR + selected cells 16.98 5.54 52.04 8.29 × 10-7
CD34 + after culture versus ΔNGFR + selected cells 2.46 0.43 14.15 3.12 × 10-1
  1. The amount of purging was evaluated in different coupled cell populations, and expressed as ratio of contaminant tumor cells (number of tumor cells pre purging/number of tumor cells after purging).
