Table 3. The value analysis of several main predictors of PAF in general.
Predictors of PAF | HR | 95% CI | P value |

hs-CRP | 1.15 | 1.04-1.24 | 0.002 |
WBC count | 1.423 | 1.067-1.897 | 0.016 |
SUA | 2.804 | 1.466-5.362 | 0.002 |
ECHO parameters | |||
LAE | 2.34 | 1.27-4.32 | 0.007 |
LAD | 1.077 | 1.014-1.144 | 0.015 |
ECG parameters | |||
Pd | − | − | <0.001 |
Clinical index | |||
Female, gender | 2.00 | 1.02-3.92 | 0.043 |
HTN | 3.127 | 1.269-7.706 | 0.013 |

CKD (S4 and 5) | 2.18 | − | 0.009 |
APT (≥4 mm) | 9.514 | 3.419-26.105 | <0.001 |
Duration of AF | 1.010 | 1.001-1.018 | 0.025 |
Type of AF | 2.412 | 1.042-5.584 | 0.040 |
In contrast, younger age (<50 yrs) (HR 1.05; 95% CI, 1.01 to 1.09) and lack of persistent AF (HR 3.27; 95% CI, 1.0 to 10.7) were each independent predictors of freedom from AF (data sources: all data in this table are from literatures in Table 2 in this paper). PAF, paroxysmal atrial fibrillation; HR, hazard ratio; 95% CI, 95% confidence interval; CRP, C-reactive protein; SUA, serum uric acid; LAE, left atrial enlargement; LAD, left atrial diameter; Pd, P wave dispersion; HTN, hypertension; IHD, ischemic heart disease; CKD (S), chronic kidney disease (stage); APT, aortic plaque thickness; AF, atrial fibrillation.
