Statistical analysis
Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) version 23 for Windows. Categorical data were presented as numbers and percentages. The compliance of continuous data with normal distribution was evaluated with the Shapiro-Wilk test. Continuous data conforming to non-normal distribution were presented as median and interquartile range values. Pearson’s chi-square or the Pearson exact test was used in the comparison of categorical data. The Mann-Whitney U test was used in the comparison of continuous variables. The univariate regression analysis was performed to evaluate the factors associated with a positive pelvis urine culture, and the parameters that were found to be significant at this stage were further examined using the multivariate analysis. A value of p < 0.05 was considered statistically significant.
