Odds of disease among exposed= 50×12000
Odds of diease among non exposed= 700×10000
Odds ratio= odds of exposed/odds of non exposed
Odds ratio=50×12000/700×10000= 0.086

In an industry employing 10,000 people, 2500 were employed in areas where they were exposed to pesticides, while the remaining 7500 were not exposed. At the beginning of the study, all employees were free of disease. The entire population of 10,000 was followed for 10 years to determine whether exposure to pesticides increased the risk of developing a particular disease. For this disease, the findings were present in the following table: The results of a hypothetical study of the effects...
s Question Completion Status: QUESTION 65 Please complete the calculations for the following questions. You must correctly explicitly state the including the disease/outcome, the place of interest, and the time/duration or appropriate time units (for example: "Smokers had 5.2 times the odds of having lung cancer compared to non-smokers context of your answer by A 15 year follow-up study was conducted examining the relationship between environmental tobacco smoke (ETS) and developing a myocardial infarction (MI). ETS was measured based on...
Incidence and prevalence rates can also be used to compare the rates of disease across different settings (places), people, or time. We therefore need measures of comparison. The ratio of two measures of disease frequency is called the relative risk. The difference between two measures of disease frequency is called the risk difference, or rate difference. In some cases, it involves a measure in an exposed group (or groups) and a measure in an unexposed or comparison group. In other...
9. When you desire to study the effects of a rare exposure on a disease using observational methods, you would optimally employ the type of study design. Remember you would likely need to conduct your study in a place where the exposure occurs. cohort b ase-control 10. Another name for a retrospective study is an) study b. cohort e experimental 11. You have completed a year long study of the effectiveness of a reading program among second graders. At the...
In your opinion, which of the below three study design is best to assess the relationship between smoking and CRC? Why? (6 sentences) No plagiarism please Cross Sectional Study 1. Verga Enterprises is conducting a study to assess the relationship between smoking and colorectal cancer (CRC). In the survey that was conducted, 20 out of 100 non-smokers had CRC, while 40 out of 60 smokers had CRC. (a) What makes this a Cross Sectional study design? This particular case is...
4. Suppose you are investigating an outbreak of an infectious disease in a small area (Region A) of a country. Your team does a random survey of 1,000 people who live in Region A and find that there are 182 cases. a) What measure(s) of disease occurrence can be calculated here? Calculate and interpret the measure(s). Calculate and interpret a 95 %CI for any measure you calculate. 5. Your boss at the Centers for Discase Control has you go back...
A GWAS (Genome Wide Association Study) study is genotyping 1,000 individuals (300 controls and 700 cases) for 500,000 different SNPs in search for genes involved in the (non-fictional) disease lupus. At position 45,897,592 of chromosome 2, the measurements are as follows for a C/T SNP: -control individuals: 50 C : 550 T -case individuals: 200 C : 1200 T 2.1) Is one allele more frequent among the cases compared to the controls? Which one? 2.2) To test if the difference...
I am a PSU official who is interested in the recent cohort study you (expert epidemiologist!) completed regarding the exposure of smoking and the outcome of asthma in college students at PSU. I want to know the proportion of asthma risk in PSU smokers that could be prevented if PSU smokers were to stop smoking. To provide me with an answer you will calculate which of the following: Question 6 options: A) Attributable risk in the exposed B) An odds...

Use the information below to answer questions 1-2. Leather back turtles (Dermochelys coriacea) lay 50 eggs per clutch on soft sand beaches. Let us assume that the first and second cleavage within the developing eggs is controlled by the presence of a single pair of codominant alleles, CA and C Full cleavage and development to maturity will occur if an offspring bears alleles in the heterozygous (CAC) condition. However, there is only 18% cleavage penetrance if C Cappears in the...
