AF - atrial fibrillation
Ϯ
The patients scored severity of symptoms on a 5-point Likert scale, with higher scores indicating more severe symptoms. The numbers indicate the range of scores.
*
The p value for the comparison of data with respect to the prevalence of symptoms between patients with intermittent and chronic AF. The data was compared using the chi-square test.
†
The p value for the comparison of data with respect to the symptom severity scores between patients with intermittent and chronic AF. The data was compared using the unpaired Student’s t-test.
