Seasonal

32
Q

37
Q

A

Analytical

38
Q

Method which starts with the disease and retrospectively investigates the cause

A

Case Control/Case Comparison Method

39
Q

Refers to the gathering of individuals with the disease in a case control method

A

Case group

40
Q

Refers to the gathering of individuals similar to the case group but do not carry the disease

A

Comparison (control) group

41
Q

This method prospectively studies two populations
