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.
