Figure 4. — Odds ratio of 30-day mortality in the training and validation cohorts. Presented are the odds ratio (OR) of 30-day mortality in a logistic regression model adjusting for demographics and comorbidities, with group C as the reference subphenotype. The results are presented for the 3 models in the training and validation cohorts. Group A had higher 30-day mortality in all 3 models in the training and validation cohorts. Group D had higher 30-day mortality in the GBTM model in both training and validation cohorts, and only in the validation cohort in the DTW-HC and DTW-PAM models. DTW-HC: dynamic time warping-hierarchical clustering; DTW-PAM: dynamic time warping-partition around medoids; GBTM: group-based trajectory model.
