As shown in Table 2 and Figure 1, mandated choice option was assigned the top three ranks by 54% of respondents, with an overall median score of (3 [2,6]), and was preferred over the options of donor-or-surrogate informed consent (4 [2,7], p <0.001), donor-only informed consent (5 [3,7], p <0.001), and presumed consent (7 [3,10], p <0.001).
The unchosen option is assigned a value r 1 = ρ, where ρ is a free parameter.
First, the expected consequences of each option are assigned a numerical score reflecting the strength of preference scale for each option for each criterion.
The options are assigned what is known as an "exercise price" -- the employee's cost for cashing in the reward.
Response options were assigned to keyboard letters.
As soon as informed consent is obtained, one of the treatment options is assigned to the patient.
Further, donor-or-surrogate informed consent, donor-only informed consent, and presumed consent options were assigned the top three ranks by 41%, 36%, and 25% of respondents, respectively.
Response options are assigned values from 0 to 3. According to the instructions, scores can be calculated as the number of items scored as a 2 (often or much) or 3 (very often or very much), a sum score or the mean of the non-missing items [ 24].
The option "Much better" was assigned score 5; the option "Somewhat better" was assigned score 4; and the option "Equal" was assigned score 3; the option "Somewhat worse" was assigned score 2; and the option "Much worse" was assigned score 1.
According to the answers, a categorical rank (first-line/preferred choice, second-line/alternate choice, third-line/usually inappropriate) was assigned to each option.
Since some items have multiple questions requiring a single yes/no answer, reviewers sometimes had difficulty selecting an option when partial credit was assigned.
