Abstract
BACKGROUND: Two-year safety and efficacy data were presented to the Canadian Therapeutic Products Directorate Scientific Advisory Panel, in Ottawa, Ontario, Canada. METHODS: The 955 women enrolled in the 10-year, multicenter, Mentor MemoryGel study were distributed into four cohorts: 572 augmentation patients, 123 revision-augmentation patients, 191 reconstruction patients, and 69 revision-reconstruction patients. The surgeons in the study received an intensive clinical educational program in addition to the protocol. RESULTS: Mentor's 2-year study results indicate that the risk of any complication or reoperation at some point through 2 years after implant surgery is 24.5 percent for primary augmentation patients, 30.2 percent for revision-augmentation patients, 42.9 percent for primary reconstruction patients, and 41.8 percent for revision-reconstruction patients. The rupture rates reported from the magnetic resonance imaging cohort were 0 percent for all groups. Patients reoperated on at least one time were as follows: 9.4 percent for primary augmentation, 12.8 percent for revision-augmentation, 27.3 percent for primary reconstruction, and 19.4 percent for revision-reconstruction. Also, 2.4 percent of primary augmentation patients, 7.3 percent of revision-augmentation patients, 8.9 percent of primary, and 11.6 percent of reconstruction patients had their implants removed, with patient choice and capsular contracture being the most common reasons. CONCLUSIONS: The data from the Mentor CPG Gel Study resulted in approval of these implants for general use on October 20, 2006. The educational program resulted in improved clinical outcomes and probably should be required for all surgeons using the devices.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
