Vitamin D status in symptomatic knee osteoarthritis: Association with clinical and radiographical parameters
Bibliographic record
Abstract
OBJECTIVE: We aimed to examine the relationship between vitamin D deficiency and knee osteoarthritis in women aged 45-60. METHODS: 110 female patients with knee osteoarthritis were included. Patients were divided into two groups according to vitamin D level: group 1 included 65 patients with low vitamin D (< 20 ng/ml), and group 2 included 45 patients with vitamin D in normal ranges (≥20 ng/ml). Severity of osteoarthritis was evaluated by Kellgren-Lawrence (KL). Pain, stiffness and functional status were measured by Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC). RESULTS: Rate of vitamin D deficiency was 59.09%. Mean vitamin D level was 9.09±3.82 in group 1 and 27.84±6.42 in group 2. Vitamin D was significantly lower in group 1 (p=0.00). K/L grade 1(28.89%) and 2(64.44%) were most frequently found in group 2, whereas grade 3(38.46%) and 4(15.38%) were found in group 1. Group1 had significantly higher radiographic grades than group 2 (p=0.00). Patients in group 1 scored significantly higher in WOMAC (p=0.00). K/L scores were correlated with VAS-pain and WOMAC scores (p=0.00). K/L scores showed no significant correlation with body mass index (BMI) (p=0.82).CONCLUSION: Vitamin D deficiency is associated with knee OA in terms of pain, stiffness, functional and radiological status.

How this classification was reachedexpand
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.
