Context:This assessment requires you to apply the knowledge and skills gained in all the modules to undertake a critical appraisal. You will need to appraise 3 different study designs of a topic as given OR choose a topic of your choice:Diet/ Food and Prostate cancer risk• Instructions for any option• You can choose any population/country.• You can also choose studies from different countries. For example case-control study from Asia and/or cohort study from Europe.STEPS for the Assessment1. Search the library database to find three studies that answer your research question. All three studies must be of different study designs. For instance, you could include cross-sectional, case-control, cohort and RCTs. Systematic reviews and literature reviews are not allowed. These studies do not have to prove their hypothesis or agree with each other. Please note that marks will be deducted if all identified papers are of similar study.2. Critically appraise all three articles you found. Your answers are to be written in the tables provided to you which was based on CASP checklist and other types of checklist (JBI checklist for cross-sectional study).3. In the tables provided to you in the checklist on blackboard page of your class under Assessment 3, you are required to answer either “Yes”, “No”, “Unclear”.4. For each of the answer of “Yes”, “No” or “Unclear”, you will need to provide the “Evidence” that you found in the article to support your answers.5. For each of the “Evidence”, you will need to critically appraise stating your justification, compare and contrasting or/and providing solution.References: You should include all the sources you have used within your text and organize them in your reference list according to APA 6th edition style.

Did the study address a clearly focused issue?
Yes/No/ Unclear
Evidence: justification,
compare and contrasting or/and providing solution
Aim of the present study was to understand the influence of diet and nutrition on male prostate cancer. The study finds the relationship of various nutritional factors, dietary patterns and other factors influencing prostate cancer. In one of the study conducted in US it was found that obesity is linked with various cancers including Prostate cancer (Calle & Kaaks, 2004, p. 582). Many animal studies report that various nutrients, like fat, protein, carbohydrates, vitamins are related to prostate cancer (Ohwaki et al., 2012, p. 272).

Yes/No/ Unclear
Evidence: justification, compare and contrasting or/and providing solution
The confounding variables are not studied. Though one of the variables is studied that is gender but that too is not been worked properly. Just a little bit has been studied and there are various confounding variables present in the study like gender, age etc. Other confounding variables can be pregnancy, presence of a disease.

Does the comparison been made, make clinical sense?
Yes/No/ Unclear
Evidence: justification, compare and contrasting or/and providing solution
The clinical picture of various variables are studied. Obesity causes hyperulinemia and increased occurrence of bioactive insulin growth factor-1 (IGF-1), a growth factor which promotes the development of various types of cancer (Roberts et al., 2010, p. 309). With regard to IGF-1 approach, various studies shows the signaling of IGF-I, AKT, phosphoinositide 3-kinase plays a crucial role in the development and advancement of PCa (Mavropoulos et al., 2009, p. 563).
Critical appraisal questions
Underline your answer
Is there a strong association between exposure and outcome (relative risk)?
Yes/No/ Unclear
According to the present research and other recent research there is an increasing association between the variables. Animal studies have concluded that certain nutrients, like fats, proteins, vitamins (vitamins A, D,E), polyphenols and carbohydrates , are actually involved in Prostate Cancer pathogenesis, as well as advancement by a number of mechanisms, comprising antioxidant effects, as well as the impact of sex hormones , inflammation (Ngo et al., 2004, p. 1252).
