Decreased synovial fluid omentin-1 concentrations reflect symptomatic severity in patients with knee osteoarthritis
Bibliographic record
Abstract
The aim of this study was to measure omentin-1 concentrations in serum and synovial fluid (SF) of knee osteoarthritis (OA) patients and to investigate their correlation with patient-reported symptomatic severity. We enrolled 263 knee OA patients and 62 healthy controls. We collected Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores from OA patients and measured omentin-1 concentrations in serum and SF by enzyme-linked immunosorbent assay (ELISA). Our results demonstrated that omentin-1 concentrations in SF but not serum were independently and negatively correlated with self-reported greater pain and physical disability in OA patients. Omentin-1 in SF might serve as a potential biomarker for reflecting the symptomatic severity of OA.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
