Distribution of correct test responses for individual symptoms, before and after HAT training.

<p>The numbers of people providing an answer for each symptom-association varied between tests. Pre-training (Pre-) test n = 107–113, post-training (Post-) test n = 106–110, post-intervention evaluation (Eval-) test n = 54–55. “Don't know” responses were categorised as incorrect. Fever for 2 days, cough and abdominal pains are not associated with HAT. *McNemar's p-value indicates a significant (p<0.05) increase in correct associations between pre-training and post-intervention evaluation tests.
