Abstract
<p>Background: Mesenchymal stromal/stem cells (MSCs) may be a useful therapy for severe acute graft-versus-host disease (GVHD). Methods: Patients who developed steroid-refractory grade II-IV acute GVHD were randomly assigned to treatment with one infusion of third-party 2 × 10 E6/kg bone marrow (BM)-MSCs (n = 12) or placebo (n = 11). The median cell dose applied was 2.2 × 10 E6/kg (range 1.7–4.2). The median age was 37 and 47 years in the two groups (p = 0.24), respectively. Results: At day 28, the BM-MSC group had six (50%) complete responders and 2 patients (17%) with a partial response. In the placebo group, the corresponding figures were three (27%) complete and three (27%) partial responders (p = 0.68). Transplantation-related mortality (TRM) 100 days after treatment was 17% in the BM-MSC group and 27% in the placebo group. At 1 year, TRM was 33% and 36% in the two groups, respectively (p = 0.59). The 100-day survival rate was 83% in the BM-MSC group and 73% in the placebo group. Five-year survival in all patients was 42% and 45% in the two groups, respectively (p = 0.87). Conclusion: Although only a few patients were included in the trial, a single dose of BM-MSCs did not seem to be an effective therapy for steroid-refractory acute GVHD. </p>

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
