Comparison of dose estimates for subjects based upon their own responses to the questionnaire or upon the responses given by proxies.

Dose ratioa All comparisons consideredb Six outliers excludedb

N GM GSD N GM GSD
DP1 to DS 53 1.04 7.46 49 0.97 3.68
DP2 to DS 49 0.79 4.51 47 0.76 3.41

a

DS refers to the estimated dose for the subject based upon his responses to the questionnaire; DP1, DP2, and DPi refer to the estimated doses for the subject based upon the responses to the questionnaire from the first, second, or either proxy, respectively.

b

N is the number of comparisons, GM is the geometric mean of the ratio of doses, and GSD is the geometric standard deviation of the distribution of ratios.
