CORRIGENDUM TO: LACK OF ASSOCIATION BETWEEN TRANSFORMING GROWTH FACTOR BETA 1-509C/T AND +915G/C POLYMORPHISMS AND CHRONIC HEPATITIS B IN IRANIAN PATIENTS [PUBLISHED IN HEPATITIS MONTHLY. 2014 APRIL; 14 (4): E13100]

This corrigendum presents correct sentences of background and conclusions parts of abstract which contained two typographical errors.
Background: Chronic hepatitis B is one of the world’s major health concerns.
Conclusions: There was no association between TGF-b1 -509C/T and +915G/C polymorphisms with chronic hepatitis B and it seems that these changes do not play a significant role in increasing the risk of chronic infection in Iranian patients.
