Effects of vagus nerve preservation and vagotomy on peptide YY and body weight after subtotal gastrectomy

Figure 2 Correlations among vagus nerve preservation, body weight loss and peptide YY_3-36 increase. A: Vagus nerve preservation was correlated with body weight loss less than 10% [66.7% vs 0.0%, P = 0.011, odd ratio (OR) = 3.333, 95% confidence interval (95% CI) (1.293, 8.591)]; B: The vagus nerve preservation group showed significant correlation with peptide YY_3-36 level increases of less than 20% [55.6% vs 0.0%, P = 0.034, OR = 2.750, 95% CI (1.258, 6.010)]; C: Patients with body weight loss of less than 10% exhibited tight correlation with reduced elevation of peptide YY_3-36 level, typically less than 20% [83.3% vs 0.0%, P = 0.001, OR = 11.000, 95% CI (1.697, 71.282)]. PYY: Peptide YY.
