analysis of the responses of the DATTA panelists determined that the frequencies of responses (established, investigational, unacceptable, or indeterminate) differ significantly from those expected due to chance alone for questions A and B. Construction of the 95% confidence intervals comparing the established category vs the combination of investigational, unacceptable, and indeterminate showed a significant difference between these two groups for question A, indicating that the DATTA panelists believed the procedure had been established as safe. Construction of the 95% confidence intervals comparing the established category vs the combination of investigational, unacceptable, and indeterminate for question B did not show a significant difference. Ten DATTA panelists offered no opinion on question A and 11 panelists offered no opinion on B.
