The IntroductionCancer is a disease that spreads rapidly throughout the human body. There is a chance of survival if the person is at an early stage, but, in many people, by the time it can be detected is when it reaches the final stage. Additionally, rates of people developing cancers are increasing. Therefore, the inventions of cancer cures help to prolong the life of patients and increase the chances of survival. The data studied on patient survival in the drug trial. The Data First, we kindly thank StataCorp for providing the patient survival data in the drug trial. The data discusses the number of months of survival, the age of the patients and the types of drugs used during the experiments. A total of 48 patients were observed. The data clearly shows that the number of participants is quite low. This is because the cost of conducting trials and purchasing trial drugs is very high. According to the data, we measured the percentages of patient age groups to get a clear idea of ​​which age groups participate in the study most often. experience. In the survey, the highest percentages came from patients aged 60 to 69, at 54.167%. Next come 27.083% of patients in their fifties (50-59 years). Patients in their 40s (40-49 years) are the last group to participate. The percentages show that more than half of the patients are mostly elderly. The reason why the participants are mostly elderly could be that younger people are afraid to participate because there is a very high risk that patients will die during or after the trials. The data then shows the type of treatments patients received during the trials. cancer clinical trial... middle of article...... conclusion In conclusion, the analysis in this article shows that the types of medications have a negative impact on patient survival. The more effective the treatment, the fewer patients die. Patient age, on the other hand, has a moderately positive impact on patient survival. The older the patients were, the higher the risk of death. Finally, the study duration variable which indicates the duration of the trial has less impact on patient survival.ReferencesWhat is a cancer clinical trial? http:/ /www.stata-press.com/data/r8/cancer.dta
