Validity of transit time-based blood pressure measurements in patients with and without heart failure or pulmonary arterial hypertension across different breathing maneuvers (vol 24, pg 221, 2020)

After the publication of the original manuscript we found that the calculation of the supplemental data regarding the capacity of PTT-based blood pressure (BP) recordings to detect changes in systolic and diastolic BP in different cohorts of patients was incorrect. These errors occured when data were transformed from MS Excel to Sigma-Plot tables. In this correction, the affected data and the respective figures were now revised.
