  1. 1This regression also controlled for the number of hospital beds per 1,000 pop; Active Primary Care, Specialty and Psychiatry Specialty Physicians per 10,000 pop; and Census Region. The results are for a two-part model of future medical expenditures. The first part of the model uses a logit regression with the dependent variable equal to one if there were any expenditure. The second part of the model is a GLM (Gamma and log-link). Confidence Intervals were estimated using a first-order Taylor series expansion.
  2. 2Numbers in italics are statistically significant at the 5% level and that numbers in boldface are statistically significant at the 1% level.
