In a study among patients who undergo wedge resection (a type of lung surgery for early-stage lung cancer), the odds ratio between history of cardiac comorbidity (1 = cardiac comorbidity; 0 = no cardiac comorbidity) for the outcome of post-surgical complications (1 = post-surgical complications; 0 = no post-surgical complications) was 2.1. Suppose that the odds of post-surgical complications for patients without cardiac comorbidity are 1.5. The odds of post-surgical complications for patients with cardiac comorbidity is 3.15. Questions: (1) For each cardiac comorbidity group, find the proportion of patients who experienced post-surgical complications. (2) Find the value of R in the interpretation: “The probability of post-surgical complications for patients with cardiac comorbidity is R percentage points higher than that of patients without cardiac comorbidity.” (3) Find the value of R in the interpretation: “The probability of post-surgical complications for patients without cardiac comorbidity is R times that of patients with cardiac comorbidity.”

In an observational study it was found that people who had received the flu shot this year had better blood pressure readings, on average, than people who did not. Can it be claimed that the flu shot is the cause of the lower overall blood pressure? Why or why not?
A study is run to estimate the incidence of atrial fibrillation (AF) in men and women over the age of 60. Development of atrial fibrillation was monitored over a 10-year follow-up period. The data are summarized below. Using this data, compute the cumulative incidence of AF in men and in women, the relative risk of AF incidence comparing men to women, and the odds ratio of AF incidence comparing men and women. Developed AF Did not Develop AF Men 120 6453 Women 86 7074

Risk and odds ratios 1/7: Patients immobilized for a substantial amount of time can develop deep vein thrombosis (DVT), a blood clot in a leg or pelvis vein. DVT can have serious adverse health effects and can be difficult to diagnose. On its website, drug manufacturer Pfizer reports the outcome of a study looking at the effectiveness of the drug Fragmin (dalteparin) in preventing DVT in immobilized patients. Of the 1518 randomly chosen immobilized patients given Fragmin, 42 experienced a complication from DVT. Of the 1473 randomly chosen immobilized patients given a placebo, 73 experienced a complication from DVT. A) Compute the odds of experiencing DVT complications for immobilized patients treated with a placebo. (Enter the number with 4 decimal places.) B) Compute the relative risk of patients experiencing DVT complications for immobilized patients treated with a placebo (numerator) vs. those treated with Fragmin (denominator). (Enter the number with 2 decimal places.) C) Compute…

A female has a firstborn with a condition. The female's recurrence risk of a certain condition drops by 67 percent by taking a supplement regularly. 35 percent of females with recurrence are taking regular supplementation compared to 80 percent in women without recurrence. What will the female's risk in PERCENTAGE be of having a second child with the same condition?

If a test to detect a disease with prevalence of 1/1000 has a FB rate of 5% and a sentivety of 100%. What is the chance that an individual obtaining a positive a test results has the disease.
A pharmaceutical company is testing a new drug for a rare disease. In a clinical trial, 1000 patients with the disease were randomly assigned to receive either the new drug or a placebo. After one year, it was found that 60% of the patients who received the new drug experienced improvement, compared to only 40% of those who received the placebo. Is the difference in improvement rates statistically significant? Provide your rationale.
A randomized prospective study is conducted to estimate the association between taking a drug and remission for patients with a specific type of cancer. The estimated incidence rate ratio of remission for the treatment group relative to the placebo is 1.35. What is the proper interpretation of this value? An individual (from the same cancer population) who does not take the drug is 35% less likely to go into remission as compared to an individual who has taken the drug. O In a random sample of 1,000 persons from the same cancer population, there would be 350 more remissions if these 1,000 persons took the drug as compared to if they did not take the drug. O An individual (from the same cancer population) who takes the drug is 35% more likely to go into remission as compared to an individual who has not taken the drug. O In a random sample of 1,000 persons from the same cancer population, there would be 650 less remissions if these 1,000 persons took the drug as compared to if they did…
If the odds of catching the flu among individuals who take vitamin C is 0.0342 and the odds of catching the flu among individuals not taking vitamin C is 0.2653, then the individuals not taking vitamin C are 7.7573 times more likely to catch the flu than individuals taking vitamin C.
