Statistical Methods
Values were presented as mean and standard deviation, and Categorical
variables were represented by percentage and prevalence. Comparison
between patients who developed AF post cardiac surgery and those who did
not was conducted using t- test or Mann Whitney U for the continues
data, and Chi Squared Test for categorical data. Logistic regression
analysis was used for identifying pre and intraoperative risk factors
for developing AF post cardiac surgery.
Kaplan Meir survival curve was utilized for evaluating the prevalence of
AF post-surgery based on the history of pre-surgery AF. P value of less
than 0.05 was considered statistically significant.
