Trial Outcomes & Findings for NATRELLE® 410 X-Style and L-Style Breast Implants Continued Access Study (NCT NCT01870869)

NCT ID: NCT01870869

Last Updated: 2020-06-22

Results Overview

The investigator rated their satisfaction with the participant's breast implant for each breast on a 5-point scale (1=Definitely dissatisfied, 2=Somewhat dissatisfied, 3=Neither satisfied or dissatisfied, 4=Somewhat satisfied, 5=Definitely satisfied). If there was a different response for the left and right breasts the worst response was used. The percentage of participants where the investigator responded: "Definitely satisfied" or "Somewhat satisfied" is reported.

PRIMARY outcome

Timeframe: 5 years (followup after implantation that occurred between 06 May 2008 and 08 January 2015)

Population: Participants from the Evaluable population, all participants enrolled under this study protocol who received a NATRELLE® 410 X- or L-style device, with data available for analysis.

The investigator rated their satisfaction with the participant's breast implant for each breast on a 5-point scale (1=Definitely dissatisfied, 2=Somewhat dissatisfied, 3=Neither satisfied or dissatisfied, 4=Somewhat satisfied, 5=Definitely satisfied). If there was a different response for the left and right breasts the worst response was used.
