Results of the backwards binary logistic regression model investigating independent associations with self-reported brain fog.

	95% Confidence Interval for Exp(B)
Variable	OR	Lower	Upper	p-Value
Memory impairment	5.07	1.49	17.27	0.009
CFQ	1.14	1.01	1.27	0.030
Myalgia	3.82	1.21	12.04	0.022

Non-collinear variables entered on step 1 were: female sex, time since COVID-19 onset (days), memory impairment, dizziness, myalgia, CFQ score, CESD score, SRT, normal gait speed, and maximum grip strength. The model converged in eight steps and selected three independent associations.
