SECONDARY outcome

Timeframe: Baseline, 3, 6, 12, and 24 months

Population: Participants with data at the respective time point.

Patient reported quality of life outcome measure. VR-12 scores are reported as T-scores, which are standardized to have a mean of 50 and a standard deviation of 10 in the US population. Higher scores indicate better physical outcomes. Because this is a normalized range, there is theoretically no strict upper or lower bound. Most people will fall somewhere between 20-70 (+/- 3 SD).

Patient reported quality of life outcome measure. VR-12 scores are reported as T-scores, which are standardized to have a mean of 50 and a standard deviation of 10 in the US population. Higher scores indicate better mental outcomes. Because this is a normalized range, there is theoretically no strict upper or lower bound. Most people will fall somewhere between 20-70 (+/- 3 SD).
