Criterion	Assessment	More information
Process
1.Has information available about the updating policy.	Met	If a major piece of research is published which should be practice changing, we may consider updating our content to include this, but generally prefer evidence to have gone through an independent, high quality systematic review process.
2.Provides an indication that the shared decision aid is underpinned by evidence.	Met	Source and strength of evidence set out
3.Provides information about the levels of uncertainty around event or outcome probabilities, e.g. by giving a range or by using phases such as ‘our best estimate is.	Met	Indicates areas of uncertainty and complexity eg Clopidogrel was the first P2Y12 inhibitor to show benefit in addition to aspirin – this data is presented in charts below as the data for ticagrelor and prasugrel are too complex.
4.An equality impact assessment has been carried out to identify impact on inequalities groups.	Met	Strongly based on NICE GLs so source info subject to EQIA during development
Content
1.Provides a production or publication date.	Met	About' section dated Feb 2023
2. Provides information about country of publication.	Met	UK
3. Describes the health condition or issue for which the decision is required.	Met	Explores 7 treatments (and groups of treatments for CHD)This appraisal focuses on aspirin vs aspirin plus clopidogrel
4.States the decision that needs to be considered.	Met	whether dual antiplatelet is superior to aspirin alone
5. Provides clear information about the potential consequences, benefits and harms of each option	Met	rates of cardiovascular events and recurrent MI, vs major bleeds
6.Displays and frames options in a consistent, balanced and impartial way - for example, using the same sized font and neutral language	Met	Cates plots describe outcomes
7. Uses everyday language that is widely understood, or simpler language where necessary.	Not met (reading age over 14 for aid to be explained by HCP)	Your direct input has an average reading ease of about 17.2 of 100.
8. Shows that effort has been made to present quantitative information about risks, benefits, chance and uncertainty in a way that is understandable to people with low levels of numeracy	Met	Cates plots describe outcomes
9. Is presented in a digital format that complies with accessibility standards,	Not met	Accessible design principles employed.
