Epidemiology is basically common sense that is systemized to examine the etiology and potential prevention factors in disease. Epidemiological research employs various different types of study ( 1 - 3 ), depending on the question asked. Current studies are limited by the lack of appropriate definition of baseline pre-admission serum creatinine, quantitative estimates of long-term kidney function decline, and a large, multi-centre cohort to generalize their findings. odds ratio of 9.00. After a period of time, the investigator compares the disease rate in the exposed group with the disease rate in the unexposed group.
