A relative risk is simply the risk (or incidence rate) of disease in one group (usually the exposed) divided by the risk (or incidence rate) of disease in another group (usually the unexposed). A relative risk (or, technically, a rate ratio) of 0.043/0.088 = 0.49 can be computed from Table 2, consistent with a beneficial effect of religiousness **Rate** **Ratios** The **rate** in those using hormones was 30 / 54,308.7 = 55.2 per 100,000 person-years The **rate** in those NOT using hormones was 60 / 51,477.5 = 116.6 per 100,000 person-years Rates and ratios. The ratio is the relationship of two numbers. For example you have 2 flashlights and 5 batteries. To compare the ratio between the flashlights and the batteries we divide the set of flashlights with the set of batteries. The ratio is 2 to 5 or 2:5 or 2/5. All these describe the ratio in different forms of fractions A ratio is a comparison of two numbers or measurements, while a rate is a special kind of ratio in which the two things being compared have different units. Rates are often used when dealing with word problems and real life examples. In order to better understand these concepts and their applications, let's look at a couple examples

- 1.A rate refers to the frequency by which a certain event happens while a ratio refers to the relationship between the size, number, or degree of two or more things. 2.A rate is a comparison between two measurements of the same units while a ratio is the proportion of one thing to another
- The main difference between rate and ratio is that rate shows the amount of change undergone by a quantity with respect to another quantity, while ratio tells us how two quantities are related quantitatively. Rate has a dimension of one or more than one, while ratio is dimensionless

- Rate is based on events per person-time = incidence rate. Rate ratio = ratio of 2 incidence rates = relative rate. Rate should be limited to measures of incidence based on person-time rates, so a ratio of two such measures is called a rate ratio

A rate usually focuses on physics and chemistry, mostly measurements, terms like the measurements of speed, heart rate, literacy rate and, etc. while ratio can be of any object, thing, students or persons. Rate and ratios are very important in explaining the equivalence from one and the other. A rate cannot be one if ratio does not exist Both rates and ratios are a comparison of two numbers. A rate is simply a specific type of ratio. The difference is that a rate is a comparison of two numbers with different units, whereas a ratio compares two numbers with the same unit. For example, in a room full of students, there are 10 boys and 5 girls. This means the ratio of boys to girls is 10:5 為替レート(the exchange rate)：単位A通貨あたりのB通貨の値段; 失業率(the unemployment rate)：単位人口あたりの失業者数; など． つまり，複数のものを比べる際に共通の評価指標として使用可能なものになる．(A国，B国，C国の失業率は比較可能．) ratio

1.6 Ratio, rate and proportion (EMGT) What is a ratio? (EMGV) A ratio is a comparison of two or more numbers that are usually of the same type or measurement. If the numbers have different units, it is important to convert the units to be the same before doing any calculations.

Person-time data from prospective studies of two groups with different exposures may be expressed as a difference between incidence rates or as a ratio of incidence rates.. This function constructs confidence intervals for incidence rate differences and ratios where there are two exposures (i.e. exposed or not. Rates, Ratios, Proportions, and Percents. These four concepts are confusing to the novice. One of the reasons is because they're all quotients. That is, they are expressed as one number divided by another. Thus, when given a quotient , for example, one cannot differentiate between a rate, ratio, or proportion without more information

A rate is a special kind of ratio. It's a comparison of two terms that use different units. Let's say I can do 20 pull-ups in three minutes. We could write that like this: 20 pull-ups/3 minutes. The ratio for this rate is 25:1 or 25/1, where 25 is expressed in miles and 1 is expressed in hours. Rate Example Problem. Tonya travels 50 miles in 1 hour and 15 minutes. What is Tonya's average speed in miles per hour? So currently we have a ratio of 50 miles to 1 hour and 15 minutes 6.

The incidence rates of falls per year were 3.46 in the intervention group and 7.68 in the control group, with an incidence rate ratio equal They used a randomised controlled trial design. Participants were recruited if they were aged over 60 years, had experienced a fall while living at home or in residential care, and an emergency ambulance had been called but had not taken them to hospital * The term 'incidence rate ratio assumes that you're fitting a model with an exposure () (offset) term as well, typically specifying the time each unit was observed for, in which case instead of expected counts you have expected counts per unit time, i*.e. rates. Calling them incidence rates is terminology from epidemiology

- The risk difference and risk ratio do not have this peculiar property; we say that the risk difference and risk ratio are collapsible. However, noncollapsibility is not unique for the odds ratio; the rate difference and rate ratio are generally noncollapsible as well. This may seem paradoxical, since the rate can be viewed as a risk per unit.

In epidemiology, a rate ratio, sometimes called an incidence density ratio or incidence rate ratio, is a relative difference measure used to compare the incidence rates of events occurring at any given point in time.. It is defined as: = where incidence rate is the occurrence of an event over person-time (for example person-years): = The same time intervals must be used for both incidence rates Ratios and Rates RATIOS are used, typically, to compare two like quantities. For example, if there are 13 males and 17 females, then the ratio of males to females is 13 to 17. How to write a ratio. Ratios can be written in three different ways.

Rates are ratios, any ratio with different units in the numerator and denominator is called a rate.To solve most questions involving rates of all kinds, all we have to do is to set up an equation of the form ratio = ratio.We just match the units on each side

1.4. Ratios, Rates, and Percent Ratios and Rates. Ratio: a relationship between two numbers, expressed as a quotient with the same unit in the denominator and the numerator. There are three ways to write a ratio. The ratio of a and b is: a to b or a : b o Rate, ratio, and risk have distinct technical meanings when used in an epidemiologic context. Furthermore, their accepted meaning is not static in either usage. This can lead to linguistic disagreements, which may be settled by reference to an authoritative dictionary An incidence rate ratio is the ratio of two rates - for example e1/N1 / e2/N2 where e1 & e2 are the number of events in each population and N1 & N2 are the size of the two groups, midway through.

In a 2005 paper she argued that a large proportion - approximately 45%, around 75% in China, 20-50% in Egypt and western Asia, and under 20% in India, Bangladesh, Pakistan, and Nepal - of the overrepresentation of men could be explained by the high rates of hepatitis B carriers in Asia. 33 The rationale was that (1) hepatitis B carriers have an offspring sex ratio much more in favour of.

Maternal mortality declined by 38 per cent between 2000 and 2017 Maternal mortality refers to deaths due to complications from pregnancy or childbirth. From 2000 to 2017, the global maternal mortality ratio declined by 38 per cent - from 342 deaths to 211 deaths per 100,000 live births, according to UN inter-agency estimates. This translates into an average annual rate of reduction of 2.9. The effects of training and/or ageing upon maximal oxygen uptake ( VO(2max)) and heart rate values at rest (HR(rest)) and maximal exercise (HR(max)), respectively, suggest a relationship between VO(2max) and the HR(max)-to-HR(rest) ratio which may be of use for indirect testing of VO(2max).
