Adjusted odds ratios (OR) associated with each demographic feature
| Demographic | Model β | Adj. OR | P-value |
|---|---|---|---|
| Age – vs. high (> 63 yrs) | |||
| Mid (49–63 yrs) | 0.469 | 1.60 | 1.02 × 10− 5 |
| Low (< 49 yrs) | 0.255 | 1.29 | 1.93 × 10− 18 |
| Gender – vs. males | |||
| Females | 0.541 | 1.72 | 1.17 × 10−30 |
| Ethnicity – vs. Caucasians | |||
| African-Amer. | 0.421 | 1.52 | 3.11 × 10− 12 |
| Hispanic | − 0.475 | 0.62 | 3.95 × 10− 7 |
| Other | − 0.635 | 0.53 | 1.78 × 10− 6 |
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
