Suggestions or interventions
1 low risk
0–0.15
0–50
Small variability in weight change and daily weight increase/loss
Small variability in SBP and DBP changes and their daily increases; normal PP (around 40 mmHg)
Keep on monitoring and provide lifestyle-related suggestions (e.g., improving living habits) according to questionnaire data
2 moderate risk
0.15–0.25
50–80
Moderate and increasing variability in weight changes and daily weight increases
Moderate and increasing variability in SBP and DBP changes and their daily increases; occurrence of some large daily increases in SBP or DBP; relatively low PP (40 mmHg)
Suggestions and interventions are needed from doctor after checking patient’s physiological statistics and questionnaire data
3 high risk
0.25–1
80–100
Large variability in weight change and daily weight increase/loss
Large variability in SBP and DBP changes and their daily increases; occurrence of many large daily increases in SBP or DBP; fast SBP drops; low PP (20 mmHg) and large PP variability
