Overall rating of psychometric property (Rating), + (sufficient), —(insufficient), ± (inconsistent), ? (indeterminate). Overall quality of the evidence (GRADE), A = High (very confident that the true measurement lies close to the estimate), B = Moderate (moderately confident in the measurement property estimate), C = Low (limited confidence in the measurement property). D = Very low (very little confidence in the measurement property estimate)
