- Industry-sponsored clinical trials are legally required to only use clinical outcome measures that have been prospectively validated. True or false?If you think they would beappropriate, explain how functionalism and conflict theory couldbe brought to bear on the studyof the socialization of medicalstudents. If you don’t think oneor both of these two theoretical perspectives are applicable,explain why“Genetic testing,including genomicanalysis by DNAsequencing, is transformingmedicaldiagnostics. Technologiesfor genetic testinghave had majorimpacts on the diagnosisof disease and arerevolutionizing medicaltreatments based onthe development ofspecific and effectivepharmaceuticals.” Simplify this statement ?

Assume that you no nothing else about the factors and/or the outcomes. Please note: the values of some associations are hypothetical/imaginary, the associations are plausible a. A number of chemicals in tobacco products have been shown to induce cancers in laboratory settings b. Men employed in occupations requiring them to sweep chimneys with tars and/or mineral oils have been shown to have 200 times risk of dying from scrotal cancer compared with men not engaged in such occupations. c.
