2.5 DATA ANALYSIS
Categorical variables of pregnant women included in this study were compared using Pearson’s chi-squared (χ2) test or Fisher’s exact test when appropriate. Multivariable logistic regression models were fitted to assess correlations between potential factors and GBS colonisation and were expressed by odds ratios (ORs) and 95% confidence intervals (CIs). The level of statistical significance was set at p < 0.05. Satatistical analysis was performed using Graphpad prism version 8.0.2 sofware.
