From: Debate: A subversive view of subsets - a dissident clinician's opinion

Systolic blood pressure Control group mortality Atenolol group mortality Odds ratio 95% confidence interval
<120 mmHg 6.8% (69/897) 7.7% (63/930) 1.147 0.804-1.635
120-159 mmHg 4.3% (171/4640) 3.7% (195/4583) 0.861 0.698-1.062
≥ 160 mmHg 4.3% (73/2500) 2.9% (107/2477) 0.666 0.492-0.902
  1. Breslow-Day test: χ2 = 5.269, DF = 2, P = 0.072. Breslow-Day (low systolic blood pressure versus the other two blood pressure ranges): χ2 = 3.412, DF = 1, P = 0.065. Testing for interaction of blood pressure and study, P = 0.015.
