Tables 4-8 list the median ratings for each feature from
the questionnaires administered during both the acute
and chronic phases of the study. Acute ratings were
generally favorable for a majority of subjects with
median values of 6 or 7 for all questions. The lowest
acute response for any feature was a value of 3. Chronic
ratings generally were a lower and more variable but
most of the ratings had median values in the positive
agreement range. This variability was an anticipated
outcome given the randomized, cross-over blinded
study design during the chronic phase. Tables 9-13 list
the minimum, maximum, and median values for the two
groups (A and B) on each subjective comfort question.
Table 14 reports the overall acceptability rating for the
combined feature program, Auto UltraZoom program, and
EchoBlock for each group. Overall acceptability shows that
there was no added benefit from the combined features
compared to the auto UltraZoom alone (Table 14).
