I am having trouble understanding and interpreting relative risk in a cohort study. From my understanding, it is the ratio of the risk of an exposed group to a risk of a nonexposed group. I do not understand how to interpret the ratio if it's more than 1, less than 1, or equals 1. I do not understand what it means when something has a positive association or negative association.

    1. A cohort study was undertaken to examine the association between high lipid level and coronary heart disease. Participants were classified as having either a high lipid level (exposed) or a low or normal lipid level (unexposed). Because age is associated with both lipid level and risk of heart disease, age was considered a potential confounder, and the age of each subject was recorded. The following data describes the study participants:                               Developed CHD     No CHD EXPOSED (High lipid...

    I'm studying for the MCAT and reviewing equilibrium. I am having trouble understanding why an answer is right. In the reaction H2SO4 (aq) <--> H+ (aq) + HSO4- (aq), the pH has been increased My thought is that because the pH is increased, you are increasing the H+ concentration which is a product. If you increase a product concentration, the reaction should shift left. The answer in the book says it should shift right. Why is that?
