Abstract

fetched live from OpenAlex

AIM: Data about the optimal alteplase dose required to treat haemodialysis catheter occlusion (HDC) are scarce. The purpose of the clinical trial was to examine the effectiveness of alteplase 2 mg as compared with 1 mg in restoring HDC function. METHODS: A double-blind, randomized, controlled clinical trial was conducted in a single-centre in southwestern Ontario, Canada. Rate of clot resolution, catheter replacements, catheter stripping, and mean catheter survival time were assessed using Kaplan-Meier, Cox-proportional hazard and clustered logic regression analyses. RESULTS: On a sample of 48 haemodialysis patients who provided 252 catheter occlusion events, the rate of clot resolution at the catheter site in the 2 mg group was 85.7% as opposed to 84.9% in the 1 mg group. There were only six catheter removals and 10 catheter stripping events. Cox regression analysis revealed no difference between the two groups in the hazard of occlusion on the primary 48 observations after the initial alteplase management (P = 0.267; hazard ratio = 0.72; 95% confidence interval 0.40-1.3). Correlated logistic regression on all 252 observations indicated no difference in the rate of post alteplase clot resolution (P = 0.336; odds ratio = 2.4, 95% confidence interval 0.399-14.6) between the two groups. CONCLUSION: Alteplase 1 mg is as effective as 2 mg in restoring HDC malfunction and may result in cost reduction in haemodialysis units.

Teacher imitation

Not 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.
