Question
In a case control study investigating the relationship between the number of common melanocytic naeivi (exposure) and melanoma (outcome) were investigated and were summarised as follow: Number of melanocytic naeivi Melanoma No Melanoma > 50 139 38 0 - 50 357 438 496 476 a. Calculate the appropriate measure of association for this study design and interpret in words (4 points) b. Calculate the attributable fraction (2 points) c. Interpret the finding (2 points) d. Calculate population attributable fraction (2 points) e. Interpret your findings and discuss the assumptions necessary for respective interpretation (50 words) (2 points) In a case control study investigating the relationship between the number of common melanocytic naeivi (exposure) and melanoma (outcome) were investigated and were summarised as follow: Number of melanocytic naeivi Melanoma No Melanoma > 50 139 38 0 - 50 357 438 496 476 a.

A melanocytic nevus ia atype of lesion that contains nevus cells
some sources equate the term mole with melanocytic nevus
other sources reserve the term mole for other purposes.
the majority of moles appear during the first two decades of a persons life, with about one in every 100 babies being born with moles
Acquired moles are a form of benign neoplasm, while congential moles or congential nevi, are considered a minor malformation or hamartoma may be a at a hiigher risk for melanoma.
