Note: Variables with a p‐value <0.20 in univariable logistic regression were used for backward selection in the multivariable model, with a p‐value set at <0.05 for maintenance in the model. The model was adjusted for the intervention vs. control arm of the OPERAM trial, since the intervention aimed at reducing drug‐related admissions. The number of points for the score were attributed by dividing the coefficient by the lowest coefficient.
Abbreviations: CI, confidence interval; OR, odds ratio; SE, standard error.
