Plasma chemistry, electrolytes and high sensitivity cardiac troponin in heavy horse pulling competition: Samples on arrival (day 1), on the morning of competition (day 2, 3 or 4, depending on weight category), and 3 h after competition (number of horses indicated for each time point). The first column is based on all horses, with the other columns divided based on weight category. Median (Interquartile Range) shown
