Note: The table shows Average Treatment Effects on Treated (ATET) estimates of receiving a referral card in 2013 on health in 2017 using a matching estimator. SF12 subjective physical and mental health scores are constructed using twelve questions about general health status, mobility and ability to perform daily activities as well as emotional health. 5-year survival expectation is the subjective probability of survival in 5 years elicited using a methodology developed by Delavande and Kohler (2009). We restrict the number of matches to be at least 4 and match respondents based on their mean systolic blood pressure in 2013, limiting the distance for possible matches to be at most 10. “Distance” represent the mean of the average distances between each observation and their matches. “With controls” includes a sex dummy, age and region dummies.
