Fig. 1From: Cost-effectiveness and value of information analysis of a low-friction environment following skin graft in patients with burn injuryModel diagram. The decision node (square box) shows the option available to nurses: either to manage patients recovering from skin graft surgery on standard hospital bedding, or else place patients on low-friction ‘Silkie’ sheets. The probabilities of subsequent graft losses (%) emanate from the circular chance nodes. Expected payoffs (costs and QALYs) to the patient are in turn weighted by the probabilitiesBack to article page
