From: HLA-DR expression in neonates after cardiac surgery under cardiopulmonary bypass: a pilot study
HLA-DR expression in neonates after cardiopulmonary bypass. Each point in red represents expression of HLA-DR in patients who displayed an episode of NI. The Kruskal–Wallis test was used for comparisons of multiple groups, with Dunn’s multiple comparisons test for intergroup comparisons (preoperatively, 1, 2, 3 and 4 days after CPB) (# p < 0.05). The Mann–Whitney test was used to compare infected versus non-infected patients on day 4 (*p < 0.05)
