Optimal multivariable logistic regression model for calculating the clinical score for a diagnosis of nonbacterial osteitis from Jansson et al. [14]. Risk factors were included if the regression coefficient was statistically significant (). The total clinical score is the sum of score coefficients not equal to zero, with a range of 0–63.
