A conditional recommendation is one for which the desirable effects probably outweigh the undesirable effects (weak recommendation FOR an intervention) or undesirable effects probably outweigh the desirable effects (weak recommendation AGAINST an intervention) but appreciable uncertainty exists. This implies that not all will be best served by this recommendation and decisions can be made by the patient and caregiver based on patient values, resources and setting with a clear understanding of the ensuing harms and benefits.
