Notes: The table shows the profile label, class size, expected number of symptoms, and conditional probability of the symptoms given the classes. Numbers in bold indicates a symptom probability of >0.30. The profiles are sorted according to number of expected symptoms. The model includes direct effects between rapid heartbeat and chest pain and between urinary incontinence and urinary retention. GS includes headache, tiredness, and sleeplessness. N=36,163.
Abbreviations: GI, gastrointestinal; GS, general symptoms; MS, musculoskeletal.
