  1. aHigher PETS score = more burden. bMean of medical information, medications, medical appointments, and monitoring health scales. cMean of role/social activity limitations and physical/mental exhaustion scales. dYes/no screener used for the diet and exercise / physical therapy domains. eQuestion administered in the REP sample only (N = 200). Sample sizes may fluctuate per analysis due to missing data on PETS scales
