¹ Outcome groups are “clear/minimal residual disease” (0/1), “moderate clearance” (2), “minimal improvement, no change, worsening” (3,4,5), respectively. Data shown represent average ± s.d. for n– 1343 (outcome groups 0/1), n = 262 (outcome group 2), and n = 143 (outcome groups 3/4/5), respectively.
