Table 2 Cox models were used to estimate the effect of different anti-hypertensive therapies on infectious, inflammatory and structural outcomes

  1. Model 1 uses the first drug prescribed and follows the incidence of diagnosis up until the patient stops taking the medication. Model 2 takes into account the duration of the treatment in order to compare to emergence of disease. Diabetic-status, Flu Vaccine and Statin use are corrected for in each analysis comparing anti-hypertensive therapy. The number needed to treat (NNT) was also calculated for ACE-I and ARB use for infectious, inflammatory or structural outcomes
