plots for restracted cubic spline 5 knotes for linear mixed model after mutiple imputation

[Queran Lin]

Could any members give me some advice about how to plot a curve of blood pressure against age as the attachment? It is a linear mixed model include age, gender and a restracted cubic spline with 5 knotes after mutiple imputation. I only find the rc_spline codes for regression but not linear mixed model. Many Thanks! Roth
