Abstract
Granulocyte-colony stimulating factor (G-CSF) is used to mobilize CD34+ haematopoietic stem cells from the bone marrow to the peripheral blood. We proposed to use cell subsets induced by G-CSF to slow down disease progression in patients with amyotrophic lateral sclerosis (ALS). Patients with definite or probable ALS were assigned in a double-blind manner to receive G-CSF or placebo every three months for a year. The primary outcome measure was the functional decline, measured by the revised ALS Functional Rating Scale, Revised (ALSFRS-R) score. Secondary outcome measures included vital capacity, manual muscle strength, compound muscle action potential amplitudes, neurophysiological index, and McGill single item quality of life score (QoL). Thirty-nine patients were enrolled. Seventeen patients who received G-CSF and 18 who received placebo were evaluated. G-CSF was effective in mobilizing CD34+ to blood. The outcome measures used showed no statistically significant benefit, although there was a trend of slowing disease progression following two G-CSF treatments, as shown by lower slopes of ALSFRS-R and QoL in the first six treatment months. The treatment had no major side-effects. G-CSF administration in ALS patients caused successful mobilization of autologous bone marrow cells, but was not effective in slowing down disease deterioration.

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
