§2Design and population

§2.1Design and allocation

Design class
Randomised, double-blind, placebo-controlled, event-driven kidney outcome trial
Masking
Double-blind with independent endpoint adjudication
Arms
2
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.

Randomised total 3,533 as published. Arm-level splits are reconstructed and are not published figures.

§2.3Population

Indications. Chronic kidney disease in type 2 diabetes · Type 2 diabetes mellitus

Persistent reduction in estimated glomerular filtration rate or persistent albuminuria in the context of type 2 diabetes, staged by eGFR and urine albumin-to-creatinine ratio.

Geographic footprint. United States · Canada · Denmark · Norway · Belgium · France · Italy · Japan · Republic of Korea · Australia · South Africa · India · China.

§2.4Eligibility as the Institute reads it

  • Included. Persistent reduction in estimated glomerular filtration rate or persistent albuminuria in the context of type 2 diabetes, staged by eGFR and urine albumin-to-creatinine ratio.
  • 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.
