For each question, any response category receiving 50% or more of the panel's votes was tested for a consensus by assuming that the DATTA panel is a sample from a broader population of experts. Using exact binomial probabilities, the likelihood of the observed vote was calculated if exactly 50% of the total population of experts support that response for that question. Hence, the null hypothesis is 50% of all experts support the response, and the alternative, one-tailed, hypothesis is that more than 50% of all experts support the response. Rejection of the null hypothesis, and acceptance of the alternative, is interpreted as evidence of a majority opinion in the total population of experts, and a consensus is achieved. If no consensus was found, the categories were reorganized and reanalyzed. The definitions of "promising" and "established" include the concept of "appropriate," while the "doubtful" and "unacceptable" definitions include the concept of "inappropriate." The original five categories were thus, if necessary, reorganized into three categories, "appropriate," "investigational," and "inappropriate"; an analysis of any category with 50% or more of the vote was performed. P values for the survey responses are as follows: questions 1A, 1B, and 2A, 18 "appropriate" responses out of 26, P =.0378; question 2B, 16 "appropriate" responses out of 26, P=.1635, no consensus. There were eight panelists who offered no opinion for questions 1A, 1B, and 2A, 2B.
