Table 2 Adjusted odds ratios (OR) associated with each demographic feature

From: Association of Catechol-O-methyltransferase single nucleotide polymorphisms, ethnicity, and sex in a large cohort of fibromyalgia patients

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
  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
