Direct medical costs (Int$ 2014) per episode by CVD category (n = 42 studies). 1) For each CVD category and economic perspective (Panel a) or study scope (Panel b), the boxplot represents cost estimates from individual studies (circles), the sub-group median (vertical line in solid box), inter-quartile range IQR (distance between lower and upper hinges, which correspond to the first and third quartile) and the upper (lower) whisker extends from the hinge to the largest (lowest) observed value no further than 1.5 * IQR from the hinge; 2) Three cost estimates ranging between Int$42,000 and Int$67,000, for very complex interventions in coronary acute syndrome patients (Moleregpoom et al., 2007; Thailand), were excluded from this Figure for ease of visualization. The median cost estimated in the same study for the simplest coronary acute syndrome cases is represented
