Evaluation of the effects of EF&LLF based on MLP model. The 3-layer neural network model was constructed with all the parameters in 3–17 m rats as the input layer. a Importance of osteoporosis parameters in aging rats. b Predicted months in each group based on the established MLP model according to all parameters in aging rats. c–e Predicted months in each group based on the constructed MLP model according to the parameters related to bone mass and quality, bone formation and bone resorption, respectively. Predicted values are represented as mean ± SEM. **P < 0.01 vs. 6 m; ##P < 0.01 vs. 17 m; ※P < 0.05 and ※※P < 0.01 vs. EF&LLF.
Parameters with the normalized importance of more than 50%
