Figure 5. Dose-response relationship between total protein (A) or animal protein (B) or vegetable protein (C) and relative risk of hip fracture.

Figure 5

Solid line represents adjusted relative risk and dotted lines represent the 95% confidence intervals for the fitted trend. The adj.RR of total protein intake and risk of hip fracture is below the line of RR = 1 (A), others two adj.RRs of animal protein intake and risk of hip fracture, vegetable protein intake and risk of hip fracture is spanning the line of RR = 1 (B and C). The result is consistent to the forest plot of Figure 2, 3 and 4.
