As currently used, the Alzheimer's Disease Assessment Scale- Cognitive subscale ( ADAS-Cog) has low sensitivity for measuring Alzheimer's disease progression in clinical trials. This is easily found by using repeated measurements on the same sample performed by the same operator and using a control chart to ensure that the results are consistent. Then the probable error, r, of the indirect measurement, given that r1, r2.rn are the relative errors of the individual directly measured quantities, is given as: r= ((Q/q1)2r12) + (Q/q2)2r22 +.
