We formulated the guideline recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework (Table 1);14 they are summarized in Table 2. Along with each recommendation, we provide the supporting rationale and the values and preferences that the guideline committee prioritized, based on the existing literature and perspectives shared by primary care providers and patients.

| Very low | The true effect is likely to be substantially different from the estimate of effect. |
