D Very low The estimate of effect is very uncertain, and often will be far from the truth. Table 13 | Balance of benefits and harms When there was evidence to determine the balance of medical benefits and harms of an intervention to a patient, conclusions were categorized as follows: K For statistically significant benefit or harm, report as benefit [or harm] of drug X. K For non statistically significant benefit or harm, report as possible benefit [or harm] of drug X. K In instances where studies are inconsistent, report as possible benefit [or harm] of drug X. K No difference can only be reported if a study is not imprecise. K Insufficient evidence is reported if imprecision is a factor. Table 14 | KDIGO nomenclature and description for grading recommendations Implications Grade* Patients Clinicians Policy-makers We recommend Most people in your situation would want the recommended course of action and only a small proportion would not. Most patients should receive the recommended course of action. The recommendation can be evaluated as a candidate for developing a policy or a performance measure. We suggest The majority of people in your situation would want the recommended course of action, but many would not. Different choices will be appropriate for different patients. Each patient needs help to arrive at a management decision consistent with her or his values and preferences. The recommendation is likely to require substantial debate and involvement of stakeholders before policy can be determined. *The additional category Not Graded was used, typically, to provide guidance based on common sense or where the topic does not allow adequate application of evidence. The most common examples include recommendations regarding monitoring intervals, counseling, and referral to other clinical specialists.
