Antihypertensive drug therapy vs control

Coronary heart disease mortality + morbidity · adults aged 18‐59 years with primary hypertension (mild to moderate systolic or diastolic hypertension)

Antihypertensive drug therapy showed no clear difference in coronary heart disease mortality + morbidity compared with control (low certainty).

Antihypertensive drug therapy vs control

Withdrawals due to adverse events · adults aged 18‐59 years with primary hypertension (mild to moderate systolic or diastolic hypertension)

It is very uncertain whether antihypertensive drug therapy changes withdrawal due to adverse events compared with control (very low certainty).

Intensive periodontal treatment (subgingival SRP with or without other periodontal treatment) vs Supra-gingival scaling

Diastolic blood pressure (mmHg), change from baseline · Adults (any age/sex) with chronic periodontitis (>=5 teeth remaining; PPD >4 mm), with or without hypertension

Intensive periodontal treatment (subgingival SRP with or without… probably leads to lower change in diastolic blood pressure (DBP, mmHg) compared with supra-gingival scaling (moderate certainty).

Intensive periodontal treatment (subgingival SRP with or without other periodontal treatment) vs Supra-gingival scaling

Endothelial function (flow-mediated dilation) · Adults (any age/sex) with chronic periodontitis (>=5 teeth remaining; PPD >4 mm), with or without hypertension

Intensive periodontal treatment (subgingival SRP with or without… led to higher endothelial function (flow-mediated dilation) compared with supra-gingival scaling; GRADE not reported.
