The phrase "a prevalence based on" is correct and usable in written English.
It can be used when discussing the frequency or commonness of something that is determined by a specific factor or criteria.
Example: "The study revealed a prevalence based on socioeconomic status, indicating that lower-income families faced higher health risks."
Alternatives: "a frequency determined by" or "a commonality reliant on".
However, clinical anthropometrics are well-known to be poor for estimating VAT, and, thus, it is not surprising that there is a discrepancy between a prevalence based on waist circumference and one based on more precise CT measurements (8).
We excluded diseases from the analysis that had a prevalence based on the diagnosis history of less than 0.001.
A more pronounced difference in prevalence based on one versus two days of sampling was only observed for microscopic detection of P. falciparum, where prevalence increased by 24%.
This sample size was based on herd-level Se and Sp (calculated from pooled-test Se and Sp values determined in the validation study) [ 8], a herd-level prevalence based on a previous study of 73% [ 4], and a participation rate of 50% for farms enrolled in the study during a 10 week collection period.
As an example, the expected prevalence of 22q11.2 deletions in schizophrenia is about 1%, 65, 181 but a pooled estimated prevalence based on large consortium-based case-control studies is approximately 0.3%.
A number of papers have made the "atomistic fallacy" [ 16] of inferring that migration is a driver of HIV prevalence based on individual-level studies showing a correlation between migration and HIV prevalence [ 17- 23].
Rather than accept lifetime prevalence estimates made directly from epidemiological studies, thereby ignoring evidence of recall bias that is likely to affect such estimates [ 13], an estimate of the probable lifetime prevalence based on a combination of incidence and prevalence data from Kruijshaaar [ 3] was used.
There are several other studies which also could not find a difference in PCOS prevalence based on sexual orientation (De Sutter et al., 2008; Smith et al., 2011).
Age was not consistently reported across the studies, with some giving mean ages only, others reporting ranges, and others breaking age down into categories; thus, a comprehensive analysis of prevalence based on age could not be made.
The size of these target populations constrains the viability of an ideal public health perspective to reduce AD prevalence based on a scalable approach, with interventions first targeting risk factors and then pharmacologic treatment in a highly selected group of individuals [ 9].
Only two studies have reported the prevalence of cardiovascular disease (CVD), and one of these has estimated the prevalence based on a projection.
