Term from vocabulary, not used
Small sample size did not provide adequate power. Even with the limited sample size, total lesion counts provides a more reliable view of the study data due to the greater number of lesions to work with.
Certain Agreements
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
