Figure 1. Change in bone turnover markers, vitamin D, and parathyroid hormone over two years, by treatment group.
A. Serum levels of C-terminal cross-linking telopeptide of type-1 collagen (CTX) B. Serum levels of procollagen type 1 N-terminal propeptide (P1NP) C. Serum levels of 25-hydroxy vitamin D (25OHD)D. Serum levels of intact parathyroid hormone (iPTH). AZT+NVP = zidovudine+nevirapine; TDF+LPVr = tenofovir+lopinavir/ritonavir; * p≤0.01; ** p=0.05.
