Pairwise meta-analysis
Detailed results of the pairwise comparisons (DHCA vs Mild HCA, DHCA vs
MHCA, MHCA vs Mild HCA) are reported in Figures 2, 3 and 4. Compared
with mild HCA, DHCA and moderate HCA were associated with significantly
higher postoperative mortality (odds ratio (OR), 1.92, 95% CI,
1.20-3.07 and OR, 1.41, 95% CI, 1.04-1.92, respectively). Furthermore
DHCA was associated with higher postoperative incidence of stroke, when
compared with mild and moderate HCA (OR, 1.47, 95% CI, 1.04-2.08, and
OR, 1.49, 95% CI, 1.21-1.83, respectively).
