Comparison between patients undergoing PCW+drain after positive PCW and those undergoing sternotomy for cardiac OIS of 1–3. Median and IQR displayed for continuous variables, and quantity (%) for categorical variables. omparison using Fisher’s exact test and Wilcoxon rank-sum with p<0.05 was considered statistically significant
