Abstract

fetched live from OpenAlex

Objectives: The aim of our study is to compare the Canadian Head CT rule to New Orleans Criteria, to find a more efficient guideline in predicting the important CT findings in mild Traumatic Brain Injury (TBI) cases. Study Design: Observational study. Setting: Tertiary Health Care Facility in Karachi, Pakistan. Period: 6 months from June 2017 to December 2017. Material & Methods: We divided a sample of 150 mild TBI patients into two groups of Glasgow coma scale (GCS) scores of 13-14 and GCS score of 15. Then using a separate scoring system for both the CCHR and NOC, we evaluated their accuracy and efficiency in predicting mild TBI through a total of 7 major clinical items. Specificity and sensitivity were calculated to compare both the scoring systems and results were compared through univariate and multivariate analysis. A p value of less than 0.05 was considered to be statistically significant. Results: We analyzed the relation between clinical items and important CT findings and found that the CCHR, through multivariate analysis, was more closely associated with important CT findings. We also found that the factors of age, and the Glasgow comma scale score were also strong indicators of important CT findings regardless of which guideline was used. Conclusion: In our study, we found CCHR to be a stronger predictor of important CT findings than the NOC. We found that CCHR performed significantly higher than the NOC.

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.
