Figure 1. Mental Composite Score (SF-36) plotted over time, by gender and social support (low support = 25th percentile; high support = 75th percentile). Plots are calculated with coefficients from the model fit to the entire data set. Because of the interaction of Interpersonal Support Evaluation List (ISEL) and gender, plots are created using upper and lower quartile values of ISEL as reference points. SF-36 = Medical Outcomes Study—Short Form 36.
