CRP and Peptic ulcer: The final logistic regression model was constructed as follows: Logit (P) = −0.812 + 0.036 × (Heart Rate) −0.032 × (Systolic Blood Pressure) + 2.989 × (History of Peptic Ulcer) + 2.213 × (Presence of Liver Disease) + 0.114 × (Albumin) −0.048 × (Hemoglobin) −0.011 × (Platelet Count) + 0.122 × (CRP) (Table 2).
