Incidence Rate: This is the number of new cases of a disease or condition in a specific population at risk during a given time period. It measures the rate at which new events occur in a population. It is typically expressed per unit of population and time, such as cases per 1000 person-years. Prevalence Rate: This measures the proportion of individuals in a population who have a specific disease or condition at a specific point in time or over a specified period. It reflects both new and existing cases and provides a snapshot of the disease burden in the population at a given time. Mortality Rate: This is the number of deaths due to a specific cause or overall in a population within a certain time period, often expressed per 1000 or 100,000 individuals per year. It helps in assessing the severity of diseases and the overall health status of a population. Odds Ratio (OR): This is a measure of association between an exposure and an outcome. It represents the odds that an outcome will occur given a particular exposure, compared to the odds of the outcome occurring in the absence of that exposure. It is commonly used in case-control studies. Confidence Interval (CI): This is a range of values, derived from the sample data, that is likely to contain the value of an unknown population parameter. A 95% CI, for example, means that if the same population were sampled many times, approximately 95% of the CIs calculated from those samples would contain the true population parameter. It provides an estimate of the precision of the sample estimate. Number of new cases per population at risk in a given time period is a definition of which of the following? A) Incidence rate * B) Prevalence rate C) Mortality rate D) Odds ratio E) Confidence Interval
