a
Logistic regression model statistics: Cox–Snell R2 = 0.163, Nagelkerke R2 = 0.265. The goodness-of-fit test of Hosmer and Lemeshow: χ2 = 6.100, df = 8, p = 0.636. Discrimination accuracy = 84.2%.
b
Duplicate diagnoses are present.
c
This variable represents the main complaint of a participant being physical (and not non-physical) in nature.
