*The assumed risk is the observed risk in the reference (control) group. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).

GRADE Working Group grades of evidence
High quality: Further research is very unlikely to change our confidence in the estimate of effect.
Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
Very low quality: We are very uncertain about the estimate.

Legend
ABPM: ambulatory blood pressure monitoring; BP: blood pressure; CI: Confidence interval; CV: cardiovascular; NA: information not available (data sparse or absent); eGFR: estimated glomerular filtration rate; MD: mean difference; RR: Risk Ratio.

1. Wide confidence intervals.

2. Only reported by less than half of the studies.
