The presence of α‐thalassaemia trait blunts the response to hydroxycarbamide in patients with sickle cell disease
Bibliographic record
Abstract
Hydroxycarbamide (HC), although a key drug therapy in sickle cell disease (SCD), does not result in a clinical response in all patients. Increases in fetal haemoglobin (HbF) and mean corpuscular volume of erythrocytes are standard clinical measures of HC efficacy in SCD. Genetic studies have determined that the majority of HbF regulation occurs outside the beta-globin locus. Approximately 30% of SCD patients have co-inherited alpha-thalassaemia resulting in hypochromic and microcytic erythrocytes. We provide data from 30 SCD patients (10 with alpha-thalassaemia) demonstrating that co-existing alpha-thalassaemia significantly affects several standard measures of HC efficacy in SCD.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
