Background two popular operational definitions of frailty, the frailty phenotype and Frailty
index (FI), are based on different theories. Although FI was shown to be superior in …

The frailty index (FI) quantifies frailty as deficit accumulation. It has been adapted to employ
laboratory test data (FI-Lab). Our objective was to systematically review and meta-analyse …

Objectives To conduct a systematic review of the literature on prospective cohort studies
examining mortality risk according to frailty defined by FRAIL scale, and to perform a meta …

Frailty is a complex manifestation of aging and associated with increased risk of mortality
and poor health outcomes. However, younger individuals (under 65 years) are less-studied …

Background Current guidelines for healthcare of community-dwelling older people advocate
screening for frailty to predict adverse health outcomes, but there is no consensus on the …

Background: the frailty index (FI) is an approach to the operationalisation of frailty based on
accumulation of deficits. It has been less studied in Europeans. Objective: to construct sex …

Background Although research productivity in the field of frailty has risen exponentially in
recent years, there remains a lack of consensus regarding the measurement of this …

Frailty is associated with multiple adverse health outcomes, including mortality. Several
methods have been used to characterize frailty, each based on different frailty scales. These …

Background Frailty index (FI) is a well-established predictor of all-cause mortality, but less is
known for cause-specific mortality and whether familial effects influence the associations …

In elderly populations, frailty is associated with higher mortality risk. Although many frailty
scores (FS) have been proposed, no single score is considered the gold standard. We …
