In our study, we find that although there were no significant differences in mortality between patients with low creatinine values and others at 30 days post-admission, there appeared to be a trend toward significance at one year when patients were identified based on the admission values, and a highly significant difference when the patients were identified based on pre-admission creatinine values.

The sentences
The differences did not reach statistical significance (p-values of 0.107 and 0.068 for 30 days and one year, respectively) when compared to patients with normal or high creatinine values based on admission values where the 30-day mortality was 11.11% (N = 11) or 36.36% at one year (N = 36).
