结局指标
主要结局
Percentage of Subjects Expressing Satisfaction With the Procedure
时间窗: 6 months post-treatment follow-up visit
Subject satisfaction as determined by the completion of a questionnaire at the 6 month follow-up visit, and, as requested, any other follow-up visits.
Change in Fat Layer Thickness of the Treated Flank
时间窗: Baseline and 6 months
The change in fat layer thickness as demonstrated by measurement of fat layer layer thickness using ultrasound images taken in the treated area and on the contralateral flank (control) at baseline and at the 6 month follow-up. Data collected on the untreated side and the treated side will be combined to determine the normalized change in fat layer thickness for each subject. The mean percent fat layer reduction across all treatment groups will be presented, as well as for each treatment group.
Percentage of Correctly Identified Pre-treatment Photographs
时间窗: Baseline and 6 months
Change in the treated vs. untreated areas will be assessed for changes in surface contour and/or fat volume by an independent photo review of pre-treatment and post-treatment images of the control and treated flanks. Reviewers will be practicing dermatologists. All reviewers will be blinded to post-treatment vs. baseline and/or untreated flank. The order in which images will be presented will be randomized; for each subject placement of the baseline, pre-treatment image will be randomized for each pair of subject images. Reviewers will be asked to select the baseline photos for each subject photo series and record selections on a data collection form.Criteria for evaluable photos for the purposes of the independent review: subject completed treatment regimen; subject has complete set of baseline photos; subject has a complete set of post-treatment photos; photos were taken using Zeltiq standard procedure. Results reflect the percentage of correctly identified images.
