Jmp pro software ver 15

The Kaplan–Meier method was used to estimate the survival probabilities of patients until death from any cause and recurrence. Kaplan–Meier plots were generated while stratifying by peritoneal cytology results and surgical procedures, and log-rank tests were used to assess the difference in survival between them. Continuous variables are expressed as the median (interquartile range) or mean ± standard deviation. The Mann–Whitney U test was used to compare continuous variables, and Fisher’s exact test was used to compare frequencies. A Cox proportional hazard model with the relative risk (RR) and 95% confidence interval (CI) was used for the multivariate analysis. Differences with P values less than 0 0.05 were considered statistically significant. JMP Pro software (ver.15, SAS Inc., Tokyo, Japan) was used for the statistical analysis.

Data are presented as the median and range based on their distribution. Survival analysis was performed using the Kaplan–Meier method. JMP Pro software ver. 15 (SAS Institute Inc., Cary, NC, USA) was used for statistical analysis.
