Risk factors for OC impairment
cognitive impairment, anxiety, PTSD, depression, cognitive deficit
REGRESSION
The screening analysis of demographic and clinical factors showed that only age and cognitive reserve differed significantly between groups with and without impaired OC, showing that the patients with objective cognitive deficit were older and had lower cognitive reserve than those without this deficit. No significant differences were found between patients with and without impaired OC in perception of cognitive deficit. There were no significant differences in anxiety, depression and PTSD between groups with and without objective cognitive impairment. No other differences were found (further information can be found in Additional file The final logistic regression model explained 10.3% of the variance. Only cognitive reserve reached statistical significance, being inversely related to the impairment in OC (OR = 0.878; 95% CI 0.779–0.988;
