The authors retrospectively analyze the data of 355 patients, wherein one misses a comparative account of the serum albumin (SA) levels in the cohort developing CIN (n = 63) as opposed to those without CIN (n = 292).1 The importance of the former is heralded by the Wiedermann et al meta-analysis suggesting a causal association between hypoalbuminemia and acute kidney injury (AKI), emanating from a total of 43 studies and 68,262 subjects.2 Notably so, the meta-analysis included 8 studies with 4,344 patients combined from either cardiac surgical or PCI settings.2 This evidence concerns the gene ALB and cervical squamous intraepithelial neoplasia.
