↵* Adjusted OR from GEE model estimating the odds of receiving a PG test for each categorical variable, adjusted for all variables listed and for age and age-squared.
↵** Measured in the 5 years prior to the start of period.
↵† Measured in the year prior to the start of period. RA: rheumatoid arthritis; SES: socioeconomic status; GC: gluco-corticosteroids; PG: plasma glucose; GEE: generalized estimating equation.
