Effect of colonisation with a M. catarrhalis on colonisation with S. pneumoniae, b S. pneumoniae on colonisation with S. aureus. a Shows the correlation between the determinant (colonisation with M. catarrhalis) and outcome variable (colonisation with S. pneumoniae), after adjustment for age, sex and month of inclusion, calculated using a logistic regression model. b Shows the correlation between the determinant (colonisation with S. pneumoniae) and outcome variable (colonisation with S. aureus), after adjustment for age, sex and month of inclusion, calculated using a logistic regression model
