The most common examples include recommendations regarding monitoring intervals, counseling, and referral to other clinical specialists. The ungraded recommendations are generally written as simple declarative statements, but are not meant to be interpreted as being stronger recommendations than Level 1 or 2 recommendations. Grade Quality of evidence Meaning A High We are confident that the true effect lies close to that of the estimate of the effect. B Moderate The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different. C Low The true effect may be substantially different from the estimate of the effect. D Very Low The estimate of effect is very uncertain, and often will be far from the truth.
