From: Reducing the risk of impaired bone apposition to titanium screws with the use of fibroblast growth factor-2−apatite composite layer coating

Fig. 5

Weibull plots of the bone apposition rates for the six titanium screw groups. Weibull plots of bone apposition rate for Ti (a), 25F0 (b), 25F0.5 (c), 25F1 (d), 25F2 (e), and 37F4 (f) show the probabilities (S) of resulting in a bone apposition rate in the range of 0 to σ (%). The y and x of regression lines represent lnln [1/(1 − S)] and ln σ, respectively
