Figure 1. Comparisons of active treatment and controls

Figure 1: Effects of ACE inhibitors and calcium antagonists compared to placebo and more intensive compared to less intensive blood pressure lowering regimens on of the risks of major vascular outcomes and death

Footnotes
Abbreviations - ACE-I, angiotensin converting enzyme inhibitor-based regimen; CA, calcium antagonist-based regimen; More, more intensive blood pressure lowering regimen; Less, less intensive blood pressure lowering regimen; mmHg, millimetres of mercury; 95%CI, 95% confidence intervals.
1. Overall mean blood pressure difference (systolic/diastolic) during follow-up in the actively treated group compared to the control group, calculated by weighting the difference observed in each contributing trial by the number of individuals in the trial. The negative values indicate lower mean follow-up blood pressure levels in the first-listed treatment groups (i.e. ACE, CA., more).
