Notes: data were presented as mean ± standard deviation or median (25th and 75th percentiles) according to distribution normality. Normally distributed parameters of three groups were compared using one-way ANOVA test, whereas non-normally distributed parameters were compared using Kruskal–Wallis test, with Bonferroni adjustment for post hoc analysis. Categorical variables: Pearson’s chi-square test was used for comparisons among three groups. aStatistical significance between groups A and B. bStatistical significance between groups A and C. BMI, body mass index; CRP, C-reactive protein; MPV, mean platelet volume; MPV/PLT, mean platelet volume to platelet ratio; NLR, neutrophil-to-lymphocyte ratio; PLR, platelet-to-lymphocyte ratio; PLT, platelet count.
