Fig. 1From: Frailty in randomised controlled trials for dementia or mild cognitive impairment measured via the frailty index: prevalence and prediction of serious adverse events and attritionDistribution of the frailty index (comparing ‘physical’ and ‘physical & cognitive’ frailty indices): This figure shows the distribution of frailty in each of the included trials, as modelled using a generalised gamma distribution. Pink shading indicates the frailty index comprised only of physical deficits, and blue shading indicates the frailty index combining physical and cognitive deficitsBack to article page
