*p Value for Tukey’s or Games-Howell post hoc test in relation to no Dx (reference group) for continuous variables.
†ANOVA or Welch test p value for continuous variables and Pearson's χ2 p value for dichotomous variables.
ANOVA, analysis of variance; DBP, diastolic blood pressure; HR, heart rate; HUT, head-up tilt test; no Dx, no diagnosis; OH, orthostatic hypotension; POTS, postural tachycardia syndrome; SBP, systolic blood pressure; VVS, vasovagal syncope.
