  1. Logistic regression modelling the log odds of FM in the FM group compared to the non-FM group showed significant differences in age, gender, and ethnicities. Model β coefficients are the log (adjusted ORs). An individual in the mid age group, female, and African-American would have the most increased odds of FM (adjusted OR = 4.18) compared to someone who is in in the high age group, male, and Caucasian
