Treatment difference in VAS pain at each time point: Adjusted Mean With 95% CI (ITT Population). Includes all post-baseline VAS scores prior to withdrawal and up to (but excluding) the assessment made at the last visit day. Adjusted means and CIs were derived from a repeated measures ANCOVA model with an auto-regressive first-order structure, with treatment, time, country, gender, and treatment × time as factors and baseline VAS pain as a covariate. ANCOVA, analysis of covariance; ITT, intent-to-treat; NTG, nitroglycerin; VAS, visual analog scale.
