This was statistically a highly significant difference ( P < 0.001, chi-squared analysis).
This was statistically a highly significant difference ( P < 0.001, chi-squared analysis).
Analysing the outcomes of patients with raised troponin levels compared with those with normal values (summarised in Table 2 ), the presence of an elevated serum troponin I was associated with a shorter duration of stay although this did not reach statistical significance ( P = 0.12, unpaired t test).
However, the apparent difference between the groups in numbers of organs failed did not achieve significance ( P = 0.35, t test).
