Table 2. Johnson-Neyman significance regions for perceived stress predicting telomere length at values of physical activity minutes.

Number of minutes of physical activity	Log-odds for perceived stress	SE	Confidence interval (LLCI,ULCI)
0	2.31	.94	.45,4.17
10	2.04	.84	.40,3.68
21	1.76	.74	.32,3.22
32	1.50	.67	.19,2.80
42	1.22	.62	.00, 2.42
53	.95	.62	−.24, 2.15

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.
