FOR	WEAK	There is a lower degree of clinical certainty in the balance between benefits vs. harms (e.g., net benefits) of this patient-care strategy. The majority of well-informed patients would most likely choose this patient-care strategy, compared to alternative patient-care strategies or no treatment.
AGAINST	WEAK	There is a lower degree of clinical certainty in the balance between benefits vs. harms (e.g., net harms) of this patient-care strategy. The majority of well-informed patients would most likely not choose this patient-care strategy, compared to alternative patient-care strategies or no treatment.
AGAINST	STRONG	There is a high degree of clinical certainty in the net harms of this patient-care strategy. The vast majority of well-informed patients would most likely not choose this patient-care strategy, compared to alternative patient-care strategies or no treatment.
