Abstract
BACKGROUND AND OBJECTIVE: It is unknown whether oesophageal disease is associated with systemic sclerosis-associated interstitial lung disease (SSc-ILD) severity, progression or mortality. METHODS: High-resolution computed tomography (HRCT) scans from 145 SSc-ILD patients were scored for fibrosis score, oesophageal diameter and presence of hiatal hernia. Fibrosis asymmetry was calculated as: (most affected side - least affected side)/(most affected side + least affected side). Mixed effects models were used for repeated measures analyses. RESULTS: Mean fibrosis score was 8.6%, and most patients had mild-to-moderate physiological impairment. Every 1 cm increase in oesophageal diameter was associated with 1.8% higher fibrosis score and 5.5% lower forced vital capacity (FVC; P ≤ 0.001 for unadjusted and adjusted analyses). Patients with hiatal hernia had 3.9% higher fibrosis score, with persistent differences on adjusted analysis (P = 0.001). Oesophageal diameter predicted worsening fibrosis score over the subsequent year (P = 0.02), but not when adjusting for baseline fibrosis score (P = 0.16). Oesophageal diameter was independently associated with mortality (P = 0.001). Oesophageal diameter was not associated with asymmetric disease or radiological features of gross aspiration. CONCLUSION: Oesophageal diameter and hiatal hernia are independently associated with SSc-ILD severity and mortality, but not with ILD progression or asymmetric disease. Oesophageal disease is unlikely to be a significant driver of ILD progression in SSc.

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
