The association of COVID-19 status and BMI-sex interaction with HRV circadian rhythm. A Daily HRV pattern and B mean and 95% CI for the MESOR, Amplitude, and Acrophase for subjects with COVID-19 positive or negative status. C Daily HRV pattern and D mean and 95% CI for the MESOR, Amplitude, and Acrophase for each combination of biological sex by BMI category. Time (h) is indicated by the x-axis while HRV (ms) is indicated by the y-axis. Stars indicate significant differences, with (+p < 0.1; *p < 0.05; **p < 0.01; ***p < 0.001)
