From: Predicting mortality in acutely hospitalised older patients: the impact of model dimensionality
SHAP values of the top twenty haematological and biochemical contributions to the best predictive model. A higher SHAP value indicates a higher risk of death for the feature value indicated in the colour map. Note that lower albumin, glomerular filtration rate, alkaline phosphatase, urea, and creatinine, and microcytic haematological features offer the greatest support to the model, in line with sensitivity to the somatotrophic state
