Hi Lanbo lme_lowessPlot shows a time plot of the lowess regression curve for each group in your study (two groups in this case). The curve for each group is a smooth estimate of the trend in the mean response over time for that group. This is only used for visualization purposes and can help in selecting the best model for the mean for the subsequent LME-based regression analysis.

Hope that helps-Jorge
