How did sympathovagal balance change for the sample from baseline to the CONVIRT testing phase?

The LF/HF measures decreased during the CONVIRT phase, reflecting a general reduction in sympathetic dominance across the entire sample.

What baseline differences were observed between male and female participants regarding overcommitment and LF/HF?

Compared to men, women exhibited higher overcommitment and lower LF/HF (indicating lower sympathetic dominance) at both phases.

Why did the researchers dichotomize the ERI variable into an ERI group variable?

The dichotomization at 1 aligns with theoretical health risk thresholds and helps manage outliers in a relatively low-stress sample.
