*Lifestyle changes will be less than the total sum of its subcategories as one decision aid may have multiple options.
†Percentages for the criteria to lower the risk of making a biased decision and criteria for indicating quality in IPDAS V.3 do not have counts because these items have an N/A response option, so using raw counts would not be an appropriate comparison.
‡These are mean and SD percentage values.
