Fig. 2.

(A) Responses for modified version of SAQ7 (Seattle Angina Questionnaire, short form) at baseline, 6 months and 12 months follow-up. Individual panels highlight responses to each question at baseline, 6-month follow up and 12 month follow up. Note that as these were otherwise healthy patients, without a diagnosis of ischemic heart disease, and not prescribed regular or as required nitroglycerin, the question with regard to nitroglycerin was omitted. (B) Responses for EQ-5D-5L (EuroQol 5-dimension 5 level) quality-of-life questionnaire at baseline, 6 months and 12 months follow-up. Individual panels highlight responses to each question at baseline, 6-month follow up and 12 month follow up. The final panel displays the mean overall “Health Score” at baseline, 6 months and 12 months.
