Abstract
We have studied the growth of erythroid bursts in methylcellulose cultures from bone marrow (7 cases) and peripheral blood cells (17 cases) of patients with primary acquired refractory anemias. In most cases, erythroid burst-forming units (BFU-E) were either absent or present in lower than normal numbers, and these levels remained low to absent in sequential studies. In 2 patients, circulating BFU-E were initially higher than normal, but subsequently declined to normal levels. 1 patient had low-normal numbers of circulating BFU-E initially, but these declined to zero in a later study. No clinical or routine hematological features permitted distinction between patients with initially high BFU-E and those with initially low or absent BFU-E. These findings parallel those reported for granulocyte-macrophage progenitors in refractory anemias, and support the concept that erythroid progenitor cells in these disorders are influenced by the disordered hematopoiesis.

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
