All analyses were performed with SPSS 23 statistical software for windows (SPSS Inc., Chicago, Illinois, USA). P < 0.05 was considered to be statistically significant. Data were presented as mean with standard deviation (SD) or as percentages when appropriate. In case of non-normal distributed, data were presented as median with interquartile range (IR). One-way ANOVA were used to compare normally distributed and the Mann Whitney U test for non-normally distributed continuous variables with Bonferroni correction for multiple testing. A Pearsons chi-square (χ2) test was used to investigate whether distributions of categorical variables differed from one another. We used a Kaplan–Meier survival curve to investigate the mortality rates for each of the cardiac risk groups, comparing outcome using log rank analysis. A univariate logistic analysis of the postoperative complications was performed to identify risk factors early mortality. All important variables from univariate analysis for mortality were entered in a multivariate regression analysis.

The variables were reported as the total number of procedures performed. The percentage value of the difference between the procedures for all the categories investigated for RA and H (X and Y) was calculated by this formula: Y-X/Y.
To compare the variables, this analysis assumed that the data came from two dependent samples, following the same surgical unit, treating the same disease through time and the rank sum test (Wilcoxon) was used.
The statistical significance level was set at the conventional p < 0.05. The results were analyzed using the SPSS 23 statistical software for Windows (SPSS Inc., Chicago, IL).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
