Johnson-Neyman significance regions for perceived stress predicting telomere length at values of physical activity minutes.

The Johnson-Neyman technique permits the examination of the log-odds of having short telomeres as a function of perceived stress at different values of physical activity (defined by statistical software). Confidence intervals that do not pass 0 are considered significant. As can be seen in bold, at 42 minutes of vigorous physical activity over 3 days, stress no longer significantly predicted telomere length. SE = standard error; LLCI and ULCI = lower and upper limit 95% confidence intervals, respectively.
