Survival Analysis of Continuous Outcomes

Statistical analyses were performed using the IBM Statistical Package for Social Sciences, version 21 (SPSS v. 21). Descriptive data are presented as the median and interquartile range (IQR) for continuous variables, or when appropriate, dichotomised. Survival analyses were performed using the Kaplan-Meier method and log rank test. All tests were two-tailed, and P values <0.050 were considered statistically significant.

Nonparametric Analysis of Social Data

The data obtained in this study were analyzed using the IBM Statistical Package for Social Sciences version 21 (SPSS v.21). Kolmogorov-Smirnov test was used to assess whether the data followed normal distribution or not. As the data did not follow a normal distribution, non-parametric tests were used to analyze the data. The data were expressed using medians with their corresponding lower and upper quartiles [Q1, Q3]. Categorical data were compared using the Kruskal-Wallis test or Mann-Whitney U test as appropriate. P-values < 0.05 were considered statistically significant.

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.
