Clinical assessment of malnutrition among patients with alcoholic liver cirrhosis: A single-center study in Southern China

Figure 3 Principal component analysis and serum vitamin profiles in healthy controls, hepatitis B virus-related cirrhosis, and alcoholic liver cirrhosis groups. A-C: Principal component analysis of serum vitamins showing distribution between groups. Hepatitis B virus-related cirrhosis (HBV-C) vs healthy controls (HCs) (A); alcoholic liver cirrhosis (ALC) vs HCs (B); among ALC, HBV-C, and HCs (C). Individual samples are shown as points with 95% confidence ellipses; principal components and explained variance (%) are labeled; D-L: Violin plots of serum vitamins. Vitamin A (D); vitamin B (VB) 1 (E); VB2 (F); VB6 (G); VB9 (H); vitamin C (I); vitamin E (J); VB12 (K); vitamin D (L). Horizontal lines indicate medians and interquartile ranges. ^aP < 0.05. NS: Not significant; ALC: Alcoholic liver cirrhosis; HBV-C: Hepatitis B virus-related cirrhosis; HCs: Healthy controls; PC: Principal component; Vit: Vitamin.
