The overall model fit was strong, with a pseudo-R 2 of 0.438 and a highly significant likelihood ratio test ( P < 0.000001), indicating that the model explains a meaningful portion of the variability in patient outcomes ( Table 4 ).
Conversely, a recent myocardial infarction was associated with a shorter LOS (about 6 days), though this finding was borderline significant and may be influenced by early discharge pathways (for treatment in other hospitals for coronary interventions), or mortality bias.
Other predictors, such as age, dementia, and NEWS 2 scores, showed suggestive trends but did not reach statistical significance in this model. 30-day mortality after the index DKA event This logistic regression model examined the predictors of 30-day mortality ( Table 5 ) after index hospitalisation among 318 patients (with available data).
