Restricted cubic splines are just a transformation of an independent variable.Thus, they can be used not only in ordinary least squares regression, but also in logistic regression,survival analysis, and so on. The range of values of the independent variable is split up, with "knots"defining ...
A spline is a drafting tool for drawing curves. In statistics, splines are a broad class of methods for transforming variables. I first introduce the concept via linear splines and work my way to…

The results of multivariable restricted cubic spline regression analysis showed that there was a non-linear relationship between the continuous change of BMI and hypertension (P<0.001) after adjusting the confounding factors of different genders and age groups, which indicated that there was an ...
