Abstract
Barrett's esophagus is thought to be a disease occurring predominantly in White Caucasian males of higher socioeconomic status. There are no published studies simultaneously examining risk of Barrett's esophagus according to ethnicity, gender, and socioeconomic status within a single data set. The authors conducted a retrospective case-control analysis within a cross-sectional study to determine risk of Barrett's esophagus in relation to sociodemographic variables in a large United Kingdom population. All patients undergoing upper gastrointestinal endoscopy at two clinical centers between January 2000 and January 2003 were evaluated. Data on ethnicity, age, gender, socioeconomic status, and the presence of Barrett's esophagus and esophagitis at endoscopy were collected. A total of 20,310 patients were analyzed. Barrett's esophagus was more common in White Caucasians (401/14,095 (2.8%)) than in South Asians (16/5,190 (0.3%)) (adjusted odds ratio (OR)=6.03, 95% confidence interval (CI): 3.56, 10.22), as was esophagitis (2,500/14,095 (17.7%) vs. 557/5,190 (10.7%); adjusted OR=1.76, 95% CI: 1.57, 1.97). Patients with Barrett's esophagus were also more likely to be male (adjusted OR=2.70, 95% CI: 2.18, 3.35) and of higher socioeconomic status (adjusted OR=1.58, 95% CI: 1.16, 2.15 (top tertile vs. bottom tertile)). White Caucasian ethnicity, male gender, and higher socioeconomic status are independent risk factors for Barrett's esophagus.

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
