Spss statistics software program version 25

Data are presented as the mean and standard deviation (SD) for continuous variables and the number and percentage of patients for categorical variables. The continuous results from the beginning of CR and yearly thereafter in the low- and high-eGFR groups were compared with a one-way analysis of variance followed by Tukey-Kramer's post-hoc test (Figure). The categorical variables were analyzed by the unpaired samples Student's t-test when normally distributed and Wilcoxon's ranked-sum test when not normally distributed between the low- and high-eGFR groups (Table 1, 2). P values below 0.05 were regarded as statistically significant. Statistical analyses were performed using the IBM SPSS Statistics software program, version 25.0 (IBM, Armonk, USA) at Fukuoka University Hospital (Fukuoka, Japan).

Data are expressed as medians [interquartile range (IQR), 25-75th percentile] or percentages. Continuous and categorical variables were compared between the two groups using Student's t-test and the chi-squared test, respectively. All statistical analyses were performed using the SPSS Statistics software program, version 25.0 (IBM; Armonk, USA), and time-to-event curves were plotted using EZR version 1.40 (Saitama Medical Center, Jichi Medical University, Saitama, Japan) (7 ). p values <0.05 were considered significant for all tests.
