Relationship between liver abscess incidence using (A) total number of liver abscesses or (B) liver abscess A+ (score 3) vs. virginiamycin dosage (mg/kg DM). The generalized linear mixed regression (red line) for total incidence of liver abscesses was Y = 30.5 (±0.863) – 0.419 (±0.05) × X, r² of 0.542, and SE of 4.45, and for liver abscess A+ (score 3), it was Y = 18.3 (±0.702) – 0.361 (±0.0408) × X, r² of 0.571 and SE of 3.62. The generalized nonlinear mixed regression (blue line) for total incidence of liver abscesses was Y = 30.41 (±3.72) × e^{−0.0149 (±0.0023) × X} with a half-life at 46.6 mg/kg DM, and for liver abscesses A+ (score 3), it was Y = 17.9 (±3.24) × e^{−0.022 (±0.0033) × X} with a half-life at 31.5 mg/kg DM.
