2.5 Statistics
SPSS 26.0 software was used to analyze all data. The significance of differences between the count data groups was analyzed using χ2 test or Fisher’s exact test. Continuous variables were tested for normal distribution using the Shapiro-Wilk test, and the results were expressed as mean ± SD. An independent sample T test (two-tailed) or nonparametric Mann-Whitney U test was used for comparison between the two groups, and all results with P<0.05 were considered significant differences. GraphPad Prism version 9.0.0 was used for drawing.
