Individuals that moved between reefs and zones spent variable amounts of time within protective areas.
Chemical compositions of scales [33] [34] and otoliths [20], [35] have been used to detect spawning frequency and identify individuals that spend variable amounts of time in marine habitats prior to migration into fresh water.
Some individuals complete their entire life history in freshwater whereas others, sympatric at birth, spend variable amounts of time in freshwater, estuaries, and the ocean before returning to freshwater to reproduce.
The study design means that patients will spend variable amounts of time in the study depending on the date of signing the informed consent form, the length of the enrolment period, and the date of their index episode.
The majority of the ageing population spend a variable period before death in a state of declining function, described as the frailty syndrome, representing an excess of deficits over assets in a dynamic state of balance, covering physical, functional, psychological, nutritional and social domains [48], [49], [50].
Students must spend a variable number of years in a designated area or pay fines [ 36].
At the clinical level, the majority of the aging population spends a variable period before death in a state of declining function, described as the frailty syndrome, representing an excess of deficits over assets in a dynamic state of balance, covering physical, functional, psychological, nutritional and social domains [ 142, 143].
They also reported the amount of time they spent using variable learning methods: studying lecture slides or textbooks, working in a group, creating questions, studying the pool of the students' questions and others (studying clinical guidelines, other pools of questions, web-based resources or miscellaneous).
Spending or coverage variables were time-varying covariates with a 1-year lag (2-year lags yielded similar results; data not shown).
Under these assumptions, we constructed response functions relating spending (the independent variable) to appointment attendance (the dependent variable) via CHW visits.
