Confusion matrix of the ordinal logistic regression model for differentiating severe patients from mild or moderate patients.

Severity	Mild/moderate	Severe	Total real
Mild/moderate	34	2	36
Severe	10	4	14

The model predicts 34 mild/moderate patients vs. 36 real mild/moderate patients and 4 severe patients vs. 14 real, showing an accuracy of 76%.
