Task: Answer Verification
Input (English): Question: Does urinary pentosidine predict cartilage loss among subjects with symptomatic knee OA : the BOKS Study?
Answer: Urinary pentosidine does not predict knee cartilage loss. Previous studies have suggested that local content within cartilage of AGEs is elevated in persons at high risk for progression. Our data suggest that these changes are not measurable systemically. Alternatively, urinary pentosidine levels reflect cartilage degradation in all joints (thus whole body cartilage breakdown) and may therefore not relate to OA severity in a single knee joint.
Output (English): no
