A Case-Control Study of Medication use and Acute Occupational Injury
Bibliographic record
Abstract
The purpose of this study was to test the hypothesis that workers who use medications that cause drowsiness are at increased risk of having an acute occupational injury. To test the hypothesis, a case-control study (n=1223 cases, n=1202 controls) was conducted where the sampling frame was composed of employees who had Worker's Compensation claims in one Midwestern state between March and October of 1997. Cases were employees whose cause of injury was acute (i.e. caught in, struck by, or fall). Controls, on the other hand, were employees whose cause of injury was not acute (i.e. strain injuries). The results of the study supported the hypothesis by showing that the use of drowsing medications significantly increased the risk of having an acute occupational injury (odds ratio=2.45, 95% CI = 1.00–6.01), after adjusting for 12 other risk factors. Age modified the effect such that only younger workers who took drowsing medication were at increased risk of acute occupational injuries.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
