Relative risk

The terms risks and odds are commonly reported exchangeably as if they describe the same quantity. However, statistically risk and odds have specific meanings and have different calculations, which may misinterpreted the results of a systematic review if ignored. Risk is a probability; odds on the other hand are chances or a ratio, Probability is the likelihood of an event or outcome to occur in relation to all possible events or outcomes. For example, by flipping a coin, the risk that you will get heads is 1 win out of 2 total possible outcomes or 50%. Relative risk and also called risk ratio compares risk of an event or exposure with those without exposure, e.g. the relative risk of getting caries for sugar consumers compared to non-sugar consumers. Relative risk depends on the incidence of an event given that we already know the exposure state of its participants. It can…

What, if any, variables did they adjust for? Why did they adjust for these variables? Education level, leisure time of physical activity, smoking status and age, serum cholesterol and triglycerides. This occurred because the women who were lost were older. 3. Results Table 1 Review each of the…

compare the risk of bad outcomes in patients receiving the intervention and those receiving the control. The most common methods used in expressing information about treatment options and risk reductions are absolute risk, absolute risk reduction, relative risk and relative risk reduction. Absolute risk reduction (ARR) or Risk difference (RD) is the most practical and useful method to interpret research results and is most important in clinical decision making. However, the relative risk and…

Personal Philosophy After completing the leadership inventory, I came to find that I had equal amounts of each of the four leadership styles. Personally, I thought my primary leadership style was analytical and my secondary leadership style was supportive.
