CAN is also seen in conditions such as Parkinson\u2019s disease. Normative reference data for cardiovascular autonomic function are used to stratify individuals into those with and without CAN. However, reference thresholds for both cardiovascular autonomic reflex tests (CARTs) and heart rate variability (HRV) are scarce and based on small sample sizes. The aim of the study was to establish contemporary normative reference thresholds based on a large non-diabetic population free of cardiovascular disease (CVD).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Cardiovascular autonomic function, CARTs and 5-min HRV indices were assessed in individuals without diabetes and CVD from the Lolland-Falster Health Study (2018\u20132020) by applying the point-of-care device Vagus\u2122. Age-specific normative reference thresholds were estimated by using log-transformed quantile regression models at the 5th and 10th percentile, with adjustments made for sex. Models assessing the association between age and HRV indices were further adjusted for heart rate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We present age-specific normative reference thresholds for cardiovascular autonomic function, including CARTs and HRV, for 875 individuals (48% females) aged 15\u201385\u00a0years.
