1 A Multicenter Pilot Evaluation of the National Institutes of Health Chronic Graft-versus- Host Disease (cGVHD) Therapeutic Response Measures: Feasibility, Interrater Reliability, and Minimum Detectable Change  Sandra A.

2 Figure 1 Bland-Altman plots, comparing differences (Trial 4) between clinician and expert scoring of cutaneous and oral cGVHD manifestations (difference = clinician score minus expert score) plotted against expert scores. Negative differences reflect clinician underestimation of the extent of involvement, whereas positive differences reflect clinician overestimation of the extent of involvement, relative to the expert’s assessment. A change in the magnitude of the difference between clinician and expert assessments with increasing extent of cGVHD involvement, as assessed by the expert, is determined by looking for patterns along the x-axis.

3 Figure 2 Interrater agreement between clinicians and experts for evaluation of gastrointestinal symptoms, functional performance, and cGVHD global scores. In the final 2 trials, substantial interrater agreement was observed in evaluating gastrointestinal symptoms (68% to 94% of pairwise comparisons in perfect agreement), whereas moderate to substantial agreement was noted in evaluating the 2-minute walk (75% to 80% of pairwise assessments were concordant), grip strength (60% to 77% of pairwise assessments were concordant), cGVHD global severity (clinician-expert pairs in perfect agreement 50% to 75% of the time), and cGVHD evolution over the past month (clinician-expert pairs in perfect agreement 40% to 63% of the time). Note: Numbers were rounded so that values add to 100%. Biology of Blood and Marrow Transplantation  , DOI: ( /j.bbmt ) Copyright © Terms and Conditions
