Associations between increases in RT readings by
the TSRB and the presence of health-related events
were evaluated using PROC FREQ to generate standard cross tabulation (2 × 2 tables). The “exact,”
“pchi,” and “or” statements were used to obtain odd
ratios and 95% confidence intervals with their associated Chi-squared and Fisher’s exact test results (when
appropriate based on the data distribution) to evaluate
associations between health events and RT readings for
the 2 timeframes (4 and 7 d) in this study. Statistical
significance was declared at P < 0.05.
