What is the relationship between prevalence and sensitivity?
as prevalence increases sensitivity and positive predictive value increases, negative predictive value and specificity decreases.
What is the formula of prevalence?
True Cases divided by the total Number in the population.
Can medical billing codes be used to gather statistics?
Yes, medical billing codes can be used to gather statistics as they provide standardized data on diagnoses, treatments, and procedures. By analyzing these codes, researchers and healthcare organizations can identify trends in disease prevalence, treatment outcomes, and healthcare utilization patterns. This data is valuable for public health initiatives, resource allocation, and improving patient care. Additionally, it can help in tracking the effectiveness of interventions and informing policy decisions.
Define pie chart in community medicine book?
A pie chart in community medicine is a circular graphical representation used to illustrate the proportional distribution of various components within a dataset, such as health indicators or disease prevalence. Each slice of the pie corresponds to a specific category, showing its relative size compared to the whole. This visual tool aids in quickly conveying information and facilitating comparisons among different health-related factors in a community. Its simplicity enhances understanding and decision-making in public health contexts.
What is the difference between statistical age standardisation and age-gender standardisation?
Whereas age-standardization adjusts for underlying differences in the age distribution of the combined male-female population, age/sex-standardized rates adjust for differences in the population distribution by both age and sex simultaneously.Age/sex-standardized rates are NOT the same as sex-specific age-adjusted rates.Like age, sex has a powerful influence on disease rates. Males and females have markedly different incidence, prevalence, and mortality rates for certain diseases and males have a shorter life expectancy than females.Therefore, in order to fully account for these differences, researchers may want to adjust for both age and sex when making comparisons for some conditions.The calculation for age/sex adjustment differs from age-standardization in that the individual age-specific rates are stratified by sex and are applied to the standard population stratified by sex.The requirements for the calculation of age/sex standardized rates are:Study population by age and sexStandard population by age and sexNumber of events for males and females in the study populationFormulaei(f) is the number of events for females in age group iei(m) is the number of events for males in age group ipi(f) is the number of females in age group i the study populationpi(m) is the number of males in age group i the study populationPi(f) is the number of females in age group i in the Standard populationPi(m) is the number of males in age group i in the Standard populationFor each age stratum the expected number of events is the sum of the expected number of events for males plus the expected number of events for females in that stratumAge-specific expected events= Ei=[(ei(m) /pi(m) ) *Pi(m) ] + [ (ei(f) /pi(f) ) *Pi(f) ]The age/sex Standardized Rate (per 100 000) is the sum of all expected events divided by the total standard population= [ Sum(Ei)/Sum(Pi)] * 1000
What is the relationship between prevalence and sensitivity?
as prevalence increases sensitivity and positive predictive value increases, negative predictive value and specificity decreases.
Does positive predictive value depend on prevalence of the disease?
yes
When will true prevalence be equal to apparent prevalence?
When there are no sampling errors, and the sensitivity as well as the specifity of the test equals 100%.
What are the relationship of between improper excreta and sewage disposal and the prevalence?

What is the HIV prevalence rate in Zimbabwe?
The HIV prevalence in adults is about 14.3%
What is the formula for prevalence?
Prevalence = Number of existing cases on a specific date ÷ Number of people in the population on this date. My question is as follow: The Prevalence of a recessive gene is 1:40000. What is the formula to calculate the Prevalence of that gene in a community?.Thanks.
Dominance has no direct relationship to prevalence True or False.?
True. Dominance refers to the genetic influence of one allele over another in determining a trait, while prevalence refers to how common a trait or condition is within a population. A dominant allele can be rare and still express a trait in individuals, whereas a prevalent trait can be caused by recessive alleles that are common in the population. Thus, dominance and prevalence are distinct concepts that do not directly correlate.
How do you put prevalence in a sentence?
