Most important model features associated with visits to a long COVID clinic

The top 20 features for each model are shown. Each point on the plot is a Shapley (importance) value for a single patient. The color of each point represents the magnitude and direction of the value of that feature for that patient. The point's position on the horizontal axis represents the importance and direction of that feature for the prediction for that patient. Some features are important predictors in all models (eg, outpatient utilisation, dyspnoea, and COVID-19 vaccine), whereas others are specific to one or two of the models (eg, dyssomnia or dexamethasone). Conditions labelled as chronic were diagnosed in patients before their COVID-19 index. Diabetes was not separated by type. dx=diagnosis. med=medication.
