§2.1Design and allocation

Design class
Randomised, double-blind, placebo-controlled, event-driven cardiovascular outcome trial
Masking
Double-blind with independent endpoint adjudication
Arms

Allocation
Randomised between the intervention and its comparator
Endpoint adjudication
Independent, blinded to assignment
Data monitoring
Independent data monitoring committee with access to unblinded accumulating data

§2.2Arms

Table 2. Randomised arms. Illustrative: arm-level allocations are reconstructed by the Institute from the design class and the randomised total where the published report does not state them.

§2.3Population

Indications. Atherosclerotic cardiovascular disease and cardiovascular risk reduction · Obesity and overweight in adults

Established atherosclerotic disease of the coronary, cerebral or peripheral arterial beds, or a risk profile sufficient for enrolment in a cardiovascular outcome trial.

Geographic footprint. United States · Canada · United Kingdom · Germany · Denmark · Sweden · Norway · Finland · Belgium · France · Spain · Italy · Hungary · Israel · Japan · Taiwan · Australia · New Zealand · Argentina · South Africa · China.

§2.4Eligibility as the Institute reads it

  • Included. Established atherosclerotic disease of the coronary, cerebral or peripheral arterial beds, or a risk profile sufficient for enrolment in a cardiovascular outcome trial.
  • Excluded. Participants for whom the intervention is contraindicated, including personal or family history of medullary thyroid carcinoma. Exclusion criteria narrow the population to which the estimate applies and are the principal source of indirectness where a trial estimate is applied to ordinary practice.
