Expert Solution
Introduction

The probability of the prevalence of a disease or illness during particular period time (usually 1 year) is referred to as risk. The strength of the relationship between a risk factor and outcome are measured by a factor known as relative risk (RR).

A factor that evaluates the excess risk connected with the risk factor is referred to as attributable risk (AR). A factor that measures the added risk in association with the total number of population is referred to as population attributable risk (PAR%).
