CoNS, Coagulase‐negative Staphylococcus

Numbers are the P values of significant associations between factors.

Note that shaded cells in the top row and final column indicate factors that were no longer statistically significant in the multivariable analysis (ulcer type, Wagner grade, PEDIS dept, PEDIS infection, presence of antimicrobial dressing, MRSA cultured). Whilst unshaded cells indicate factors (PEDIS perfusion, single ulcer, would duration, CoNS cultured) that remained significant. In the body of the table, ushaded cells containing a P value indicate associations where neither of the factors remained significant in the multivariable model, whilst unshaded cells indicate associations where at least one of the two factors remained significant in the multivariable model. Cells without a P value indicate non‐significant associations at the 5% level.
