Frequency threshold for reporting non-serious adverse events: 1% | |||
Notes [1] - There are no non-serious adverse events recorded for these results. It is expected that there will be at least one non-serious adverse event reported. Justification: Because the procedure is a low risk procedure, where installation is done through the existing surgical drain, and only half of the expected numbers of patients has gone through the study, no adverse event and no non-serious adverse event has occurred. |

|
|||||||
Limitations and caveats |
|||||||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||||||
Trial has been terminated early due to lack of patients going through mastectomy at the trial site in Esbjerg, leading to a smaller number of subjects analysed. |
