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 this is not for linear mixed model. Many Thanks! Roth I used normal mixed model like this: mixed sbpa age i.gender c.age#i.gender||country:, reml emonly
this is for normal mixed effects model code STATA 问题
