CrI, credible intervals.*** The difference between direct and indirect estimates was considered as an estimate of inconsistency with the null hypothesis that consistency between the direct and indirect evidence exists, and in case of presence of a statistically significant difference between the direct and indirect evidence comparison (p<0.05), rejection of the null hypothesis will be done. In case of inconsistency, net heat plot was done to assess the source of inconsistency.**** Rank statistics is defined as the probabilities that a treatment out of n treatments in a network meta-analysis, is the best, the second, the third and so on until the last effective treatment.Supplementary Table 6.

Network plot of eligible comparisons of cerebral perfusion strategies for primary outcomes and league tables for the network meta-analysis showing odds ratio (OR) and 95% confidence intervals for different outcomes among the different treatment groups in random effect models. In the network plots, circles represent each intervention as a node and lines represent direct comparisons. The sizes of circles are proportional the number of patients receiving each treatment, and the width of the lines indicate the number of studies comparing every pair of treatment. The league tables are to be read horizontally, for example, antegrade cerebral perfusion (ACP) is associated with lower post-operative stroke compared to deep hypothermic circulatory arrest (DHCA) (OR 0.62 [95%CI 0.51; 0.75]) (bold font).
