Univariate odds ratios for important model features

Shown are the relative feature importance and univariate odds ratios for the top features (union of the 20 most important features) in each model. Regardless of importance, some features are significantly more prominent in the long COVID clinic population, while others are more prominent in the non-long COVID clinic population. ·· denotes that the feature was not in the top 20 features for the model in that column. Conditions labelled chronic were associated with patients before their COVID-19 index. Diabetes was not separated by type. dx=diagnosis. med=medication. *Odds ratios exclude age, which has a non-linear relationship with long COVID.
