Table 2.
Blood laboratory values in patients with COVID-19 in relation to outcomes (discharged vs hospitalised). Data between each patient group were compared using the Wilcoxon test. Values are given as median with interquartile range in parentheses unless otherwise stated. Reference ranges are given below each laboratory value name in brackets
