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.
