Abstract
BACKGROUND: Systemic inflammation is observed in horses with heaves and could also be present in horses with a lesser degree of pulmonary inflammation. HYPOTHESIS/OBJECTIVES: It was hypothesized that racehorses with inflammatory airway disease (IAD) have increased concentration of circulating acute phase proteins. The objective of this study was to compare serum acute phase proteins of racehorses with and without lower airway inflammation. ANIMALS: Serum from 21 client-owned Standardbred racehorses with exercise intolerance and lower airway inflammation and serum from 10 client-owned Standardbred racehorses with exercise intolerance without lower airway inflammation. METHODS: In a case-control study, serum samples from previously characterized horses presented for exercise intolerance with or without lower airway inflammation based on bronchoalveolar lavage fluid cytology were analyzed for serum amyloid A protein (SAA), C-reactive protein (CRP), and haptoglobin using commercial ELISAs. RESULTS: There was no significant differences between groups for SAA (non-IAD versus IAD, median (range): 3.47 (0.06-34.94) versus 6.33 (0.06-80) μg/mL, P = .49), CRP (10.87 (2.05-29.03) versus 4.63 (0.02-31.81) μg/mL, P = .23) or haptoglobin (900.36 (607.99-2018.84) versus 749.54 (530.81-1076.95) μg/mL, P = .09). CONCLUSIONS AND CLINICAL IMPORTANCE: In this population of poorly performing racehorses in training, serum SAA, CRP, and haptoglobin were not helpful in distinguishing between horses with IAD from horses with exercise intolerance from other causes.

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
