The results of the included studies did not provide evidence to state that patients taking  antihypertensives suffer more xerostomia or hyposalivation than patients not taking them .
The case-control studies showed great variability in salivary flow , but in this case most studies showed how salivary flow is lower in patients medicated with antihypertensive drugs .
The aims of this systematic review are ( 1 ) to compare the prevalence of xerostomia and hyposalivation between patients taking antihypertensive drugs with a control group ( CG ) , ( 2 ) to compare salivary flow rate between patients treated with a CG , and ( 3 ) to identify which antihypertensives produce xerostomia .
The Cochrane Collaboration’s tool for assessing risk of bias in randomised trials
Flaws in the design , conduct , analysis , and reporting of r and omised trials can cause the effect of an intervention to be underestimated or overestimated . The Cochrane Collaboration ’s tool for assessing risk of bias aims to make the process clearer and more
