Supplementary Table S2: Absolute changes in cardiopulmonary hemodynamics following sternotomy and pericardiotomy

Absolute differences in cardiopulmonary variables at baseline with closed cest and closed pericardium to conditions after sternotomy with open chest but closed pericardium and after pericardiotomy with open chest and open pericardium. Data are presented as mean±SD or median [interquartile range] where appropriate. Groups are compared with one-way ANOVA or Friedman test with Turkey’s or Dunn’s multiple comparison post-hoc test where appropriate. Statistical analyses were performed on the absolute values and not on the differences. n=7 for all unless stated otherwise.
