§2Evidence across compounds

Every compound the Institute assesses in this indication, with the effect as recorded, the certainty rating and the contributing trials. Effects are reported on the anchor outcome where the contributing trials measured it and on the outcome the trial actually reported where they did not.

Table 1. Compounds assessed in prediabetes and progression to type 2 diabetes, ordered by certainty.

CompoundEffect as recordedInterval as reportedCertaintyTrials
LiraglutideGLP-1 receptor agonist (acylated, once-daily)Time to onset of type 2 diabetes over 160 weeks: hazard ratio 0.21HR 0.21 (95 % CI 0.13 to 0.34)Moderate1
TirzepatideDual GIP and GLP-1 receptor agonist (acylated)Progression to type 2 diabetes at 176 weeks reduced by 94 % in the prediabetes cohortHR 0.06 (95 % CI 0.03 to 0.14)Moderate1

Estimates in this table are not on a common scale and must not be subtracted from one another. Where a comparison between two compounds has been made directly, it appears in a synthesis and not here.

Figure 1. Illustrative. Compounds assessed in this indication, plotted on a common standardised axis so that direction and relative magnitude can be compared at a glance. The estimates are not on a common natural scale and the intervals are the Institute's standardised representation of the reported precision rather than published confidence intervals.

Nothing published by the Institute is medical advice, a diagnosis, a prescription, a treatment recommendation or a purchasing recommendation. Compounds supplied for research use are not approved for human or veterinary use in any jurisdiction, and a favourable analytical assessment of a supplier is not a statement that any product is safe or effective. The Institute publishes certainty ratings and never recommendations. No telephone number, messaging handle or ordering channel appears anywhere on this site.
