Gene polymorphisms associated with sudden decreases in heart rate during extensive peritoneal lavage with distilled water after gastrectomy

Figure 4 Interaction between rs820196 and smoking in patients grouped by the 30% heart rate variability cutoff. For each multifactor cell, the score of patients with heart rate variability (HRV) ≥ 30% is displayed on the left bar and the score of patients with HRV < 30% is displayed on the right bar. The high-risk interaction genotype was assigned as one and the low-risk interaction genotype was assigned as zero in the multivariable logistic regression analyses. Dark gray cells indicate high-risk combinations and light gray cells indicate low-risk combinations. No smoking = 0; smoking = 1.
