Figure 1From: Impact of low-dose prednisolone on bone synthesis and resorption in early rheumatoid arthritis: experiences from a two-year randomized studyChange in procollagen type I N-terminal propeptide (P1NP) median values (IQR) at 0, 3 and 12 months for both treatment groups. P1NP is a marker of bone formation. The difference between the treatment groups was significant both at 3 months (p < 0.001) and 12 months, (p < 0.001). 1 = baseline, 2 = 3 months, 3 = 12 months.Back to article page
