In a study by Murat et al., in which 890 patients were included, the albumin level and the development of CIN were evaluated in patients who underwent percutaneous coronary intervention (PCI), and it was revealed that the serum albumin level was lower in patients who developed CIN than in those who did not and that low serum albumin levels could predict the development of CIN [8]. This evidence concerns the gene ALB and cervical squamous intraepithelial neoplasia.
