Introduction. For My Project On Critiquing An Epidemiology

Introduction: For my project on critiquing an epidemiology study I choose to do my project on second-hand smoking and how it affects other people than just the smoking population. The article I choose was Cigarette Smoking Associated with Lung Adenocarcinoma in Situ in a Large Case-Control Study (SFBALCS). The objective of this study was â€Å"designed to understand why nonsmokers are associated with Adenocarcinoma in situ (AIS), which is common cause of lung cancer in cigarette smokers† (Bracci et al.). Statistics show that 80 % to 90% of lung cancer cases are from smoking. â€Å"Adenocarcinoma in situ (AIS), formerly bronchioloalveolar carcinoma (BAC), is not so common subtype of lung adenocarcinoma and accounts for approximately 3% to 4% of lung†¦show more content†¦They only included five counties that were located within the Bay Area which is limiting their data. By not having this part of the study so restricted it will open many other variables that are not included in the study now. Another weakness in the study is that they did not include genetic variations and susceptibility for BAC which is an important factor. With this information, it can show which people in the control and case study already have BAC in their family history which can show us the cause for why they already must disease or who will likely develop the disease later. From this information, they could have explored another direction with the AIS patients which can show us that cigarette smoke may have not been the cause of the disease developing. They also decided to not use survival biased in their study which has a big impact on their study. The reason for that is because they are just if AIS patients have good prognosis, there is no need to include survival rate. If you are conducting a study on a disease you show still include the survival rate because people can still death from this disease, even if the rates may be low. Strengths: Overall this case-control study had some good strengths which allowed the case study to successful in the aspects that it mainly covered. Overall the case study wanted
