Gal-3 and PSA concentrations were divided by their respective autoantibody levels, and the values were referred to as relative Gal-3 and relative PSA. The table shows Spearman rank correlation coefficients (rho values) and their P-values (left) between relative Gal-3 and relative PSA level for each clinical group. The fitted slope, its 90% confidence interval (CI), and P-value are also shown for the linear regression model of relative PSA and relative Gal-3 (right). A P-value of less than 0.05 was considered statistically significant and shown with asterisks (*).
