title: How to create publication quality growth curve figures (SAS or SPSS)
body: <p>I am using SAS and SPSS for a growth curve analysis and I would like to create publication quality growth curves. Below is an example of SAS code for one of my interaction models and coresponding fitted model plots:</p>
  <pre><code>proc mixed data=long noclprint covtest method=REML;
  class PID Intervention;
  model A_Score= Time Time*Time Intervention Intervention*Time Intervention*Time*Time / solution;
  random intercept Time Time*Time / sub=PID type=un gcorr;
  store out=MixedModel_A;
  run;
  ods html style=Statistical;
  proc plm restore=MixedModel_A noclprint;             
     effectplot fit(x=Time plotby=Intervention);       
     effectplot slicefit(x=Time sliceby=Intervention); 
     effectplot slicefit(x=Time sliceby=Intervention)  / clm;
  run;
  </code></pre>
  <p>I have looked at a lot of journal articles that present growth curve figures, and it is clear to me that many of them that use SAS are doing something differently from me in creating those figures, other than just selecting a different ODS HTML output style. That is, the formatting of their figures looks different than what I am able to get SAS to produce. For example, the growth curves presented in this article does not have grid lines on the plot area, and they have data point markers on the growth curves at the data collection time points: <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3042028/" rel="nofollow noreferrer">https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3042028/</a></p>
  <p>Does anyone know if there are things I can do differently in order to get closer to producing publication quality figures? I understand that some degree of manual formatting and editing will be needed, but if it is easy to get software to produce figures that are more publication-ready, I would like to know how to do so. I can easily use SAS or SPSS, as well as Excel with output from either, if relevant. Thank you</p>
