In the case of the HIV clinic, nurses collect both prevalence indicators for funders, and incidence indicators to guide clinic-level decisions.
Findings from both prevalence and frequency curves are interesting.
Both prevalence and parasitaemia were higher in the urban forest.
Both prevalence and incidence studies can be either prospective or retrospective.
We estimate both prevalence and frequency curves by different measures of crime.
Both prevalence of major complications at 30 postoperative days and mortality are highest after radical hysterectomy for cancer.
Ideally, bottom-up cost estimates are made through population-based studies in which both prevalence of headache and associated costs are determined simultaneously.
Notably, the NPV increased substantially, exceeding 94% for all methods tested at both prevalence rates.
A generalised estimating equation (GEE) approach was used to analyse both prevalence of infection and incidence of clinical episodes.
For P. falciparum, both prevalence and incidence of P. falciparum showed marked seasonality, whereas only P. vivax incidence but not prevalence decreased in the dry season.
Thus, wBol1 shows spatial variation in both prevalence and phenotype.
