Fig. 2: Incremental cost-utility results (ICUR) estimates of included studies.

Note that McManus et al.28 did not calculate an ICUR as QALY difference was insignificant. ICUR estimates in Cunningham et al.29 and Wong et al.34 were dominant. CG control group. *: asterisk denotes studies targeting populations with hypertension; studies without an asterisk include people with (pre)diabetes.
