Coefficients for Full Education or Practice show the increase in number of working alarms in the treatment arms relative to the increase in the comparison arm (Current Norm). Beliefs were assessed prior to education delivery. Case counts are lower for the regression that includes beliefs due to missing KAB survey responses.
