Is there a large medical database with symptom frequencies for diseases? I.e. the percentage of patients with a specific disease that have specific symptoms?
For example (numbers and symptoms made up by me):
- longstanding heartburn 81.3%
- dysphagia 72.5%
- hematemesis 38.1%
- unintentional weight loss 20.9%
- fever 51.2%
- fatigue 17.1%
- dry cough 66.0%
- sneezing 26.2%
- malaise 8.5%
The answer should not be several research papers that contain two or three different diseases with symptom frequencies each but a proper database containing hundreds if not thousands of diseases with symptom frequencies.
