Abstract
PURPOSE: The study assessed the sensitivity of a blood culture drawn from only one lumen of a multilumen, long-term, indwelling, central venous catheter in pediatric oncology patients. METHODS: Episodes of positive blood cultures were included if cultures were sent simultaneously from multiple lumens of a long-term, indwelling, central line and if the culture was thought to represent a true bacteremia. RESULTS: Discordant results from cultures drawn simultaneously from different lumens occurred in 13 (32%) of 41 episodes. The estimated sensitivity of a culture drawn from a single lumen was 84%. CONCLUSION: Drawing blood cultures from all lumens of these lines should be considered in this patient population.

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
