Theroetical reduction in prevalence of disease after implementing population based preventive strategies, resulting in reduction of the population mean (corrected data, see text)
| Variable | Reduction in mean values | Prevalence (%) of deviance | Theoretical reduction in prevalence (%) according to reduction in mean values | Reduction (%) according to Rose et al,3 see footnote2-150 |
| Systolic blood pressure (⩾140 mm Hg) | 5 mm Hg | 31.4 | 14.5 | 5.0 |
| Systolic blood pressure (⩾160 mm Hg) | 5 mm Hg | 9.7 | 4.0 | — |
| Diastolic blood pressure (⩾90 mm Hg) | 2.5 mm Hg | 24.6 | 8.5 | — |
| Diastolic blood pressure (⩾95 mm Hg) | 2.5 mm Hg | 12.2 | 4.4 | — |
| Body mass index (⩾30 kg/m2) | 1 kg/m2 | 15.7 | 9.0 | 6.9 |
| Alcohol intake (⩾300 g/week) | 15 g/week | 13.8 | 3.7 | 4.5 |
↵2-150 Based on table III in Rose et al 3: for alcohol intake the value used by Rose of 0.24% per ml/week has been increased by 0.8 to obtain g/week.
