The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
The liver is the body's largest organ and hepatology is a large field. It includes the study of acute and chronic hepatitis, viral hepatitis, cirrhosis, genetic and metabolic liver diseases and their complications, liver cancer, liver transplantation, drug metabolism, and immunology as it pertains to the liver. Hepatology is a branch of medicine concerned with the study and management of diseases that affect the liver, gallbladder, biliary tree and pancreas. The term hepatology is derived from the Greek word hepar that means liver and logia that means study. Hepatology has previously been considered a subspecialty of gastroenterology, but nowadays doctors can specialize in hepatology alone.
