Model 1: Probability of all-type pathologies (AP) presence as a function of total power of HRV in supine position (TP in SUP) and instantaneous variability in supine position (SD1 in SUP) adjusted by semi-season (reference category: Summer), number of observations n=419, for 18 subjects. Model 2: Probability of AP presence as a function of the high frequency component of HRV in orthostatic position assessed one week earlier (HF in OR w−1), n=288, for 18 subjects. Model 3: Probability of muscular affection (MA) presence as a function of the low frequency component of HRV in orthostatic position (LF in OR) and instantaneous variability in orthostatic position (SD1 in OR) adjusted by semi-season, n=283, for 17 subjects. AUC, area under the curve.
