A prospective cohort study was conducted over five years to explore if binge-drinking of alcohol and liver cirrhosis (a form of liver cancer) were related,using a population-based sample of adults between 20 to 60 years of age. Among 6980 adults who reported regular binge-drinking of alcohol, 1659developed liver cirrhosis during the five-year follow up period. Among those who were not involved in any binge-drinking, a total of 12383 adults, therewere 241 new cases of liver cancer diagnosed during the follow up period. Calculate a suitable measure to find out if there is infact association betweenbinge-drinking of alcohol and liver cancer. Type in only your final answer with two decimals, please.

In a random sample of 678 adult males 20 to 34 years of age, it was determined that 58 of them have hypertension (high blood pressure).
The Joint Commission on Accreditation of Healthcare Organizations mandated that hospitals ban smoking by 1994. To study the effects of this ban on smoking behaviors, subjects were randomly selected from two different populations: those from hospitals with the ban and those from hospitals without the ban. Investigators were interested in determining if this smoking ban had any impact on the proportion of smokers employed at each hospital that then quit smoking. Among 843 smoking employees of hospitals with the smoking ban, 56 quit smoking during the study period. Among 703 smoking employees from workplaces without the smoking ban, 27 quit smoking during the study period. Below is the Stata output that was run to determine if there was a statistically significant difference between these two proportions at the α=0.05 level. A. What is the estimate of the proportion of smokers from the hospitals that implemented the ban that quit smoking (the blank labeled "C" in the above output)?…
Twelve subjects with diagnosed hypertension were randomly selected for this study. The age at which they were diagnosed were recorded and listed below. Based on the data, is there any evidence that the age at diagnosis is not equal to 45.0 years?
A study investigated the joint effects of sleep quality and sleep duration on the development of coronary heart disease (CHD). A total of 60,586 individuals aged 40 and older with no current or prior history of CHD were enrolled into the study. A self-administered questionnaire was used to collect information on sleep quality and duration at the start of the study, and 43,910 participants reported getting ³6 hours of sleep per day. Participants were followed for approximately 12 years, for a total of 152,000 person-years among those getting <6 hours sleep/day and 527,000 person-years among those getting ³6 hours sleep/day. Out of 2,740 participants who developed CHD throughout follow-up, 721 participants reported getting <6 hours of sleep per day at baseline. Question 10: What is the incidence rate of coronary heart disease among all participants in the study?
A colonoscopy is a medical procedure that is designed to find and remove precancerous lesions in the colon before they become cancerous. The article “Association of Colonoscopy and Death from Colorectal Cancer” reports that in a sample of 10,292 people diagnosed with colorectal cancer, 7.1% had previously had a colonoscopy. In a sample of 51,460 people without colorectal cancer, 9.8% had previously had a colonoscopy. 25. Can you conclude that the percentage of people who have had colonoscopies is greater in those without colorectal cancer? Use ? = 0.01
A study was made of 1,057 cases of poisoning in children treated as inpatients at Milwaukee Children's Hospital from 1962 through 1968. Data on date of occurrence, age and sex of the child, and type of agent involved were recorded and analyzed by standard statistical methods. Poisoning was due to ingestion of aspirin in 35 per cent of the children studied and to the ingestion of hydrocarbon distillates in 18 per cent. A statistically significant male dominance was found for ingestion of hydrocarbons; age-specific peaks were found for some categories. Trends as to the relative and absolute frequencies of each specific poison from one year to the next were noted; possible reasons for increasing or decreasing trends are discussed. Is this study descriptive or inferential? Explain your answer. What are the variables used in the study? In your opinion, what level of measurement was used to obtain the data from the variables? Does the article define the population? If so, how is it…
The researchers sought to explore the connection between dietary fat consumption and the incidence of cardiovascular disease (CVD) events in a cohort of 5,115 young adults of both Black and White backgrounds. In 1985, these individuals underwent an initial examination. Over the subsequent 35 years, those who were initially free of disease were monitored to investigate the potential associations between their dietary fat intake and the occurrence of CVD events. Among the 2,100 young adults who had a high-fat diet at the start of the study, 255 experienced a new CVD event. Among the 3,015 young adults who did not have a high-fat diet at baseline, 125 experienced a new CVD event during the follow-up period. Risk of CVD events among those with a high-fat diet is ____. Risk of CVD events among those without a high-fat is ____. The relative risk is ____.
