TP53 and sarcopenia: Furthermore, in this investigation the probability of sarcopenia was modeled; P represented the probability that the event of sarcopenia will occur, with a number between 0 and 1, according to TP53 gene polymorphism, age, and PBF:(1)P(X,Y,Z)=ln⁡π(X,Y,Z)(1−(X,Y,Z))=−2,4030−0,0379∗(X1−X3)+1,0018∗(X2−X3)+0,017∗Y+0,0728∗Zπ(X,Y,Z)=eP(X,Y,Z)/(1+e(X,Y,Z)).
