The Shapiro–Wilk test was applied to each group to assess normality. A one-way analysis of variance (ANOVA) was conducted to compare groups with normally distributed data. A comparison of RIN^e values between fresh 0 and 3 h postmortem intervals (PMI) was performed using a two-sample t test. Differences in cell type proportions across groups were analyzed using chi-square tests.
