Procedural volume between 2012 and 2017

Monthly volume was adjusted for the average length (days) of months during the study period, i.e., 30.4 days (10.1 weekends and 20.3 weekdays) per month. Dotted lines and shaded area represent estimates and 95% CIs derived from Poisson regression models (see Table 1). ACS, acute coronary syndrome; CLI, critical limb ischemia; SA, stable angina; IC, intermittent claudication; STEMI, ST-elevation myocardial infarction; NSTEMI, non-STEMI; UA, unstable angina.
