Example. “Comparable mean reductions in systolic and diastolic blood pressures were achieved. Treated systolic blood pressure ranged from 128+/-6 mmHg to 130+/-8 mmHg. For diastolic blood pressure the range was 86+/-3 to 88+/-2 mmHg. (values are expressed as mean +/- SD). Since the clinical study showed no difference in benefit between the treatment alternatives, the economic analysis was based on difference in costs only.”
