POTS: postural orthostatic tachycardia syndrome. Values are given as number and percentages or median and interquartile ranges. Differences are calculated by Fisher’s exact test and Mann–Whitney U test. β Coefficient and 95% confidence interval (CI) (continuous variables) or odds ratio (OR) and 95% CI (categorical variables) are given after adjustment for age and sex by generalized linear model or logistic regression. for trend was given for dichotomous variables, except for marital status. was considered statistically significant.
