Figure 2. Mental Composite Score (SF-36) plotted over time, by gender and Belonging (ISEL) subscale (low belonging = 25th percentile; high belonging = 75th percentile). Plots are calculated with coefficients from the model fit to the entire data set. Because of the interaction of Belonging and gender, plots are created using upper and lower quartile values of Belonging as reference points. SF-36 = Medical Outcomes Study—Short Form 36.
