Box plots showing BNP levels (in logarithm) in patients according to the summed stress score (a) and (b) and angiographic severity (c). According to summed stress score, patients were grouped as mild (between 4 and 8), moderate (9–13), and severe (>13). Boxes show median and interquartile ranges and bars represent upper and lower range limits.
