Spss 17.0 statistical package for windows

Statistical analysis was performed with SPSS 17.0 Statistical Package for Windows (SPSS Inc, Chicago, Illinois, USA). Continuous variables were given as the median±standard deviation, and categorical variables were defined as percentages. Data were tested for normal distribution using the Kolmogorov- Smirnov test. Categorical variables were compared with chi-square test. Student t-test or Mann-Whitney U test was used to compare continuous variables. Mean values were compared by ANOVA, followed by Tukey HSD test among different groups. Pearson’s correlation analysis was performed to define the correlation between hs-CRP levels and the (NLR). The receiver operating characteristics curve was used to demonstrate the sensitivity and specificity of NLR and the optimal cut-off value for predicting RMVS. In order to define the relationship between RMVS and possible confounding factors, univariate and multiple logistic regression analysis was performed. A p value of <0.05 was accepted as statistically significant.
