  1. Intraoperative variables and outcomes of the 189 premature infants who had PDA ligations performed in the operating room (OR) or the neonatal intensive care unit (NICU). For continuous variables, standard deviations are listed in parentheses. For categorical data, the number of cases is given, followed by the percentage in parentheses. The percentage may not equal given number divided by n due to missing data for certain outcomes
