Table 9.
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 |
DPi to DS | 102 | 0.91 | 5.94 | 96 | 0.86 | 3.54 |
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.
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.
