Sequential changes in WOMAC pain scores for reparagen (red, n = 48) and glucosamine sulfate (blue, n = 47). Both treatments resulted in a significant reduction in WOMAC pain levels within one week of treatment (p < 0.001) compared to baseline values. Sustained administration resulted in a time-dependent decrease in pain scores (p < 0.001)
