Colinearity between covaiates which were significantly associated with HAP.

Abbreviations: HABAM = Hierarchical Assessment of Balance and Mobility, ABX = antibiotics, orgs. = organisms. Variables which were co-linear (correlation estimate >0.20) are highlighted in boldface. The higher the number, the stronger the correlation. Negative correlation estimates mean the variable on the ‘y’ axis was associated with a lower score of the variable in the ‘x’ axis (e.g. higher Charlson index was associated with a lower or worse HABAM/mobility score). Where covariates are binomial (e.g. Admitted from hospital/institution, a negative correlation estimate refers to that event NOT having happened (e.g. higher HABAM/mobility score was associated with not having been admitted from hospital/institution, or in other words, having been admitted from home.). Covariates in the ‘y’ axis have been abbreviated to make viewing the table easier. Colinearity between covaiates which were significantly associated with HAP.
