Analyses were performed using the SPSS statistical software program for Windows version 21 (SPSS Inc., Chicago, IL, USA). Comparison of the means was performed using Student’s t-test and one-way ANOVA, followed by Tukey’s multiple comparison test for continuous variables. The survival data for both groups were analyzed by means of the Kaplan-Meier method and the log-rank test was used for the assessment of the difference between the two groups. Two-sided P <0.05 was considered a statistically significant difference.

Statistical analyses were performed using the SPSS statistical software program for Windows version 21 (SPSS Inc., Chicago, IL, USA). The association between variables was tested using Pearson’s χ2or Fisher’s exact tests for categorical variables. The survival data were analyzed using the Kaplan-Meier method and the log-rank test was used for assessing differences between groups. Two-sided values of P <0.05 were considered to indicate statistically significant differences.
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.
