Variables associated with cognitive complaints at 1-month follow-up in logistic regression models.

	Univariable analyses		Multivariable analysis ( n = 96)
	Crude OR (CI 95%)	p	Adjusted OR (CI 95%)	p
HADS	1.94 (1.15–3.27)	0.014	1.96 (1.08–3.57)	0.028
Age	1.04 (1.01–1.08)	0.015	1.05 (1.01–1.09)	0.026
Female sex	1.80 (0.72–4.52)	0.211	0.99 (0.33–3.05)	0.99
ICU admission	0.18 (0.05-0.64)	0.008	0.22 (0.05-0.90)	0.035
SVFT	0.95 (0.88–1.02)	0.176	0.93 (0.84–1.03)	0.152
DSST	0.98 (0.96–1.01)	0.163	1.01 (0.97–1.05)	0.611

OR, odd ratio; CI, Confidence interval; HADS, Hospital Anxiety and Depression Scale; SVFT, Semantic Verbal Fluency Test; DSST, Digit Symbol Substitution Test; ICU, Intensive Care Unit. Odds ratios for HADS are given for an increment of one interquartile range (iQr). The SVFT score is the number of correct generated words in 60 s and the DSST score is the number of correctly matched symbols in 120 s. Bold values indicate statistically significant associations.
