Abstract
OBJECTIVE: As the fiberoptic gastroscopy using midazolam is being in widespread use, the exact nature of midazolam on memory should be clarified. We intended to examine whether midazolam causes selective anterograde amnesia and what impact it has on other aspects of memory and general cognitive function. METHODS: We recruited healthy subjects undergoing fiberoptic gastroscopy under conscious sedation. At baseline, history taking for retrograde amnesia and the Korean version of the Montreal Cognitive Assessment were performed. A man's name and address were given immediately after intravenous midazolam administration. After gastroscopy, the subjects were asked to recall those items. By the time they had fully recovered consciousness, the same test was repeated along with the Korean version of the Montreal Cognitive Assessment and a test for retrograde amnesia. RESULTS: A total of 30 subjects were enrolled in this study. Subjects with high-dose midazolam showed lower scores in the immediate and delayed recall of "a man's name and address" compared with those with low-dose midazolam. The midazolam dose was inversely correlated with the delayed recall scores of "a man's name and address." On full recovery of consciousness, the subjects did not exhibit any of anterograde or retrograde amnesia. CONCLUSIONS: These findings suggest that midazolam causes transient selective anterograde amnesia in a dose-dependent manner.

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
