  1. Responses from baseline survey at Southcentral Foundation. Binary outcome logit model where wrist device = 1 and arm device = 0. Estimated with robust standard errors
  2. aMarginal effects are interpreted for continuous regressors as elasticities at the mean where the dependent, outcome variables and independent variables change at a constant rate. The categorical variables are the marginal values taken as an approximate percentage effect of the variable in response to a discrete change from zero to one, while holding all other parameters constant
