Table 2.

Correlation coefficients between different pairs of thrombi parameters. A correlation pair is defined by parameters of row and column of the corresponding cell. Above the table diagonal cells are shown Pearson correlation coefficients, while below them are shown Spearman correlation coefficients. Cells with the absolute value of the correlation coefficient higher than 0.5 are highlighted in green, while those between 0.3 and 0.5 are highlighted in yellow. To better distinguish between Pearson and Spearman correlation coefficients, the diagonal elements are written in red.
