Basic laboratory results were also collected, showing elevated kidney function markers (creatinine, cystatin C, urinary albumin/creatinine) in patients with CKD and increased indicators of liver damage (aspartate aminotransferase (AST), alanine transaminase (ALT), gamma-glutamyl transferase (GGT)) and lipid profile among patients with HTN compared to healthy controls. Here, GPT is linked to hypertensive disorder.
