Data not shown for patient categories were not likely to adhere to therapy and not likely to return, as values did not reach statistical significance except for the following: Not likely to adhere to therapy: late patients, odds ratio 6.04, p value <.01; unemployed patients, odds ratio1.65, p value .04. Not likely to return: late patients, odds ratio 14.13, p value <.01. Marginal effect: the change in the probability of the outcome compared to the reference group
*Target blood pressures are based on the JNC VI guidelines, which were current at the time of the study
†Patient age divided by 5. Odds ratio and marginal effect reflect change associated with a 5-year increase in age
BP = blood pressure, ref = reference group
