ERRATUM
In the article by Akpek et al entitled "Development of a
prognostic model for grading chronic graft-versus-host disease," which appeared in the March 1, 2001, issue of Blood (Volume
97:1219-1226), there was an error in the way the prognostic factor
score (PFS1) at diagnosis of chronic graft-versus-host disease was
quoted. The correct cutoff points for PFS1 should have been 0 (no risk factor), 1.9 and below (TP and/or PTO), above 1.9 and not
above 3.5 (ESI with or without TP [or PTO]), and above 3.5 (all 3 factors). These cutoff points apply to all statements about
PFS1 in the abstract, main text, and Figure 1B. The authors apologize
for this unfortunate error.
