Univariate analysis identified older age (mean 63.4 vs. 48.9 years, p=0.010), diagnosis of diabetes mellitus (7/21 vs. 0/12, p=0.032), lower haemoglobin and albumin at index presentation (mean 105 vs. 125g L-1, p=0.007; and 22.1 vs. 27.2g L-1, p=0.040, respectively), and not attempting soft tissue coverage at index presentation (8/20 vs. 10/12 primary closure as opposed to no closure or negative pressure wound dressing, p=0.028) to be associated with an unhealed ulcer. Here, ALB is linked to diabetes mellitus.
