Figure 4

Sequential changes in WOMAC stiffness scores for reparagen (red, n = 48) and glucosamine sulfate (blue, n = 47). Both treatments resulted in a significant reduction in baseline stiffness scores from week 2 onwards (p < 0.001), but only the reparagen treated group was significant at week 1 (p < 0.01). Sustained administration resulted in a time-dependent decrease in stiffness scores (p < 0.001)
