The second column from the left depicts the semi-quantitative average score severity of all lesions taken together across left ventricle and right ventricle. The six columns to the right depict the percentage of all examined sections with the individual lesions listed: - = 0, -/+ <0.5, + = 0.5–20, ++ = 20–30, +++ = 30–40, ++++ >40.
