Data were expressed as median (IQR: 1st, 3rd quartiles) for continuous variables and n (%) for categorical ones
Differences between patients with and without pleural effusion were compared using the Mann-Whitney U test for continuous variables and Fisher’s exact test for categorical ones
There were no significant differences between patients with and without pleural effusion
