Thomsen et al. [3] reported a population search based prevalence study in Denmark, which found 105 patients with sporadic hemiplegic migraine at a prevalence rate of 0.01%.
Out of all caries-related search fields, prevalence scored the greatest number of hits in all databases.
We conducted a systematic review of studies published from January 1 , 2001 to September 30 , 2012using the search terms, "prevalence of overweight and obesity in Nigeria" or "overweight and obesity in Nigeria".
Though our systematic literature search for prevalence data retrieved 335 references, almost all were considered inappropriate due to lacking representativeness for the general population.
Based on SEARCH-derived prevalence, ∼191,986 youth with diabetes aged <20 years lived in the U.S. in 2009, including 166,984 with type 1 diabetes and 20,262 with type 2 diabetes (Table 3).
It is worth noting that the most powerful predictor of low prevalence search accuracy was high prevalence search performance.
A multiple regression model was used to low prevalence search accuracy1 from the factors high prevalence search performance, K, vigilance, attentional control, and extraversion.
Finding that high prevalence search performance is a good predictor of low prevalence search performance would provide an efficient method for predicting who would be good at low prevalence search tasks.
However, if high prevalence search performance is a good predictor of low prevalence search performance, then one could gather data about an individual's performance very quickly at a high prevalence rate and use that as a predictor of the unobserved low prevalence performance.
Importantly, both increased vWMC and higher accuracy in the high prevalence search performance predicted fewer false alarms in the low prevalence search task, and the remaining predictor variables were not significant predictors of false alarms.
