Fig. 1

Box-Whisker plots representing the differences of LV and RV strain parameters between controls and patients with suspected myocarditis. The centreline in each box represents the median, whereas the lower and upper limits of each box represent the 25th and 75th percentiles, respectively. Whiskers extend to the most extreme observations within 25th and 75th percentiles ±1.5*IQR. Observations outside these whiskers are shown as dots. LV - left ventricle; RV - right ventricle; IQR - inter-quartile-range; SR - strain rate
